Who Built Colbeck Castle

New archival evidence points to a surprising alternative.

Two miles north of Old Harbour stands one of the strangest surviving buildings in Jamaica.

Colbeck Castle is difficult to mistake for any other great house on the island. Four massive three-story towers rise from its corners. Between them run two levels of open arcades, three bays across the shorter elevations and five across the longer ones. Even as a roofless ruin, the building has the scale and presence of something designed to be noticed.

For generations, its history seemed straightforward. Colonel John Colbeck, one of the soldiers who took Jamaica from Spain in 1655, received land in the area and purportedly built the castle around 1680. Its heavy masonry and towers were explained as protection against a possible Spanish attempt to retake the island.

That is still the official version told by the Jamaica National Heritage Trust.

That timeline, however, is at odds with the political landscape of the era. The argument for 1680 rests entirely on the threat of a Spanish invasion, yet Spain had officially ceded Jamaica to England a decade earlier in the 1670 Treaty of Madrid. Pouring vast resources into a fortress against a nonexistent Spanish naval threat makes little sense. Moreover, when wealthy planters built fortified homes during this period, their defenses targeted local threats like slave rebellions and pirates—not Spanish warships.

That geopolitical contradiction undercuts the 1680 timeline. Furthermore, the documentary and architectural record increasingly suggests that Colonel John Colbeck did not build the castle at all. Instead, stronger evidence points to the massive stone structure having been built roughly eighty years later—likely in the early 1760s—by a Scottish planter named John MacLeod.

Unlike the traditional lore, this revised timeline does not rely on the name of the property or architectural guesswork alone. It is anchored by a converging chain of maps, deeds, probate records, contemporary newspapers, and physical evidence preserved in the masonry itself.

The Man Who Gave Colbeck Its Name

There is no doubt that Colonel John Colbeck belonged to the first generation of English Jamaica. Born in 1630, he arrived with the English invading force in 1655 and remained on the island, becoming a substantial landowner and serving in both military and civil positions. A 1670 survey records 812 acres under John Colebeck's name and a further 1,340 acres under “Capt. Colebeck and inhabitants,” confirming his extensive landholding in the area. His gravestone in Spanish Town recorded his arrival with the conquering army and his subsequent public service until his death in 1682, with his will proved the following year. The connection between Colbeck and the land that came to bear his name is therefore well established.

What is much less certain is whether that association with the estate later became confused with the construction of the castle—a distinction that matters. When Frank Cundall described Colbeck Castle in Historic Jamaica in 1915, even he did not present a seventeenth-century construction date as established fact, writing only that it “probably dates from the end of the seventeenth century.” Though he described its dimensions in considerable detail, he provided no contemporary record showing that John Colbeck had built it. Over time, that crucial qualification largely disappeared: “probably” became “built about 1680,” and the date became firmly attached to Colbeck himself.

Yet historians studying the building during the twentieth century repeatedly noticed that something did not fit. If such an extraordinary building had stood outside Old Harbour from the 1680s onward, why was it so difficult to find in eighteenth-century accounts? The question remained unresolved for decades until architectural historian Louis P. Nelson assembled evidence that changes the problem almost completely.

A Castle That Is Missing From the Maps

Nelson, professor of architectural history at the University of Virginia and author of the major study Architecture and Empire in Jamaica, examined Colbeck as part of a wider investigation into eighteenth-century Jamaican architecture. His conclusion was direct: John MacLeod built Colbeck Castle in the early 1760s.

One of the first pieces of evidence is unusual because it concerns what is not there. Nelson examined Patrick Browne’s 1755 A New Map of Jamaica, which drew heavily on surveys carried out between 1730 and 1749 by a surveyor identified on the map simply as “Mr. Sheffield,” along with others. Published in London in 1755, the map distinguished among different types of properties, including gentlemen’s seats, forts, sugar works, and other settlements.

In the Colbeck area, Browne’s map identifies a local gully labeled “Colbeck Gully” and marks a nearby sugar works symbol, apparently labeled “Mᶜ Cloud’s.” A Jamaica Courant notice from the previous year independently places John McLeod at Colbeck Plantation, raising the possibility that the map is identifying McLeod’s own works. Yet no “Gentleman’s Seat” is marked there. This is consistent with the argument that MacLeod had not yet established a grand residence at Colbeck, although it does not rule out the possibility that an earlier, unfinished structure was already standing. The original map is held and digitized by the Library of Congress, and a copy is shown in the sources below for direct examination.

Browne’s map is still useful evidence, but its significance is more limited. The map shows that the Colbeck area was known in some detail: it identifies Colbeck Gully and marks a nearby sugar works. The legend also includes a separate symbol for “Gentlemen’s Seats,” but no such symbol appears at Colbeck. That is consistent with Nelson’s argument that MacLeod had not yet established a grand residence there by 1755. It does not, however, rule out the possibility that an earlier structure was already standing but remained unfinished and therefore was not recorded as a gentleman’s seat.

The 1749 Purchase

On November 22, 1749, John MacLeod purchased the plantation recorded as “Colobeck” from Bernard Henry, a transaction Nelson traced to the Jamaican Island Record Office (Probates and Wills, vol. 137, p. 41). The transaction apparently included several properties, and improvements were specifically mentioned on some of them. But, according to Nelson's examination of the record, no improvements were recorded at Colbeck.

Again, an omission is not absolute proof, but consider what would have been omitted if the conventional history were correct. By 1749, Colbeck Castle would have already stood for roughly seventy years as a monumental stone residence featuring four towers, two-story arcades, and an extensive complex of outbuildings—making it one of the largest and most remarkable private properties in Jamaica. Yet the property conveyance gives no indication of such a structure. Taken together with the earlier maps, the silence becomes increasingly difficult to dismiss.

John MacLeod Takes Possession

MacLeod's presence at Colbeck can be documented soon afterward. The Jamaica Courant of June 1754 carried a property advertisement directing interested parties to several contacts, including John McLeod Esq. at “Colbeck” Plantation, in the Parish of St. Dorothy. That notice is particularly useful contemporary evidence placing MacLeod at Colbeck five years after his purchase.

MacLeod was a Scot from the Isle of Lewis, probably born around 1720–22. Scottish historian David Alston—author of Slaves and Highlanders, a major study on the deep connections between Scotland and the Caribbean—has suggested that MacLeod may have worked at Colbeck Plantation as an overseer under its previous owner as early as 1743, before eventually buying the property himself. The identification of Colbeck as a plantation is also supported by Patrick Browne’s 1755 map, which marks a sugar works labeled “Mᶜ Cloud’s” beside Colebeck’s Gully in the immediate area. By 1762 MacLeod was claiming recognition as representative of a branch of the MacLeods of Lewis, and by 1771 he was serving on the vestry of St. Dorothy.

This provides an important context for the castle. MacLeod was not merely purchasing somewhere to live; he appeared to be establishing his position within the wealthy planter society of eighteenth-century Jamaica. In the early 1760s, according to Nelson, he undertook an architectural project on a scale that few Jamaican planters could match.

The Castle’s Design Challenges the Old Story

Colbeck Castle has often been described as a fort or fortified residence, and its four towers make that interpretation understandable. But the evidence suggests that, whatever may have been standing at Colbeck in 1755, the main house had been completed sufficiently to serve as an occupied residence by the time John MacLeod died in 1775. His probate inventory records the furnishings of a wealthy household, including large bedsteads, mahogany furniture, paintings, prints, a billiard table, and a chamber organ. The building may not have been completed in every part, but the principal house was clearly in use.

When architectural historian Louis P. Nelson first saw Colbeck Castle in the summer of 1998, more than two centuries had passed and the house had long since become a ruin. The furniture, wood paneling, doors, and other fittings were gone. What remained were the masonry walls, plaster, openings, and other traces that allowed Nelson and earlier investigators to work out how the finished interior had once been arranged.

From that surviving evidence, Nelson identified a formal entrance leading into a large stair hall that had once been paneled, with double doors opening into another substantial hall. The house also contained a paneled parlor, bedchambers, upper rooms, and rooftop walks overlooking the surrounding landscape. When those physical remains are considered alongside MacLeod's 1775 inventory, Colbeck begins to look less like a simple defensive fort and much more like a grand country residence built to impress.

Nelson also found a remarkably close relationship between Colbeck's plan and designs published by the Italian Renaissance architect Sebastiano Serlio in I sette libri dell'architettura, which was available in English by the early seventeenth century. Serlio published two versions of the Poggio Reale, a grand villa near Naples. The first showed the original building as Serlio found it; the second was his own adaptation of the design. It is this second, rectangular version, shown below, that Nelson argues comes particularly close to the layout of Colbeck.

Colbeck and Serlio's adaptation share the same basic arrangement: four corner towers, with five bays between the towers on the longer sides and three on the shorter sides. Colbeck's open arcades also draw on features shown in Serlio's original Poggio Reale design. The resemblance does not tell us when Colbeck was built, because Serlio's architectural books were already known in England during the seventeenth century. Nor does it suggest that an Italian built the castle; a local or British builder could have worked from Serlio's published designs. What the comparison does suggest is that Colbeck was conceived more like a grand European country house than a simple defensive fort.

The design may have offered practical advantages as well. Serlio praised the Poggio Reale for keeping its main rooms cool during hot weather because the sun could not enter them directly. That would have made the design well suited to Jamaica. He also saw architecture of this kind as a sign of wealth, taste, and social standing. If MacLeod deliberately followed Serlio's model, Colbeck may have been designed both for comfort in a hot climate and to make a statement about status.

A House Built to Impress

The scale of MacLeod's establishment becomes clearer in the service buildings. The northwest outbuilding contained a sophisticated kitchen and washroom, with archaeological and architectural evidence indicating large fireplaces, baking facilities, stew stoves, water storage, and specialized preparation spaces, while another section incorporated a sunken cold-water bath, changing room, and privies supplied by a system of water channels. This was an elaborate residential complex, but it also depended entirely upon slavery.

MacLeod's Colbeck plantation contained 355 enslaved men, women and children at the time documented by his probate records. Nelson interprets six small chambers in one of the outbuildings as barracks-style accommodations likely used by enslaved household workers, and the inventory records cooks, washerwomen, housemaids, drivers, and others whose labor sustained the mansion and plantation. That context is essential: the grandeur of Colbeck Castle was made possible by the wealth generated by an eighteenth-century slave plantation. Its architecture displayed MacLeod's status, but the household behind that display depended on the labor of hundreds of enslaved people.

The 1775 Inventory May Be the Most Important Evidence of All

One long-standing tradition concerning Colbeck holds that the castle was never completed, perhaps never even occupied—a view still described in the National Library of Jamaica's catalog as a building that “may never have been completed or occupied.” However, MacLeod's probate records make that extraordinarily difficult to maintain. John MacLeod died at Colbeck on May 12, 1775, with London newspapers subsequently describing the “eminent planter” as having died at his “seat” and his will, proved six days later, specifically referring to his “mansion-house” (which Nelson traced through the Island Record Office to the corresponding probate inventory at the National Archives of Jamaica).

The inventory, taken on August 1, 1775, describes a fully functioning elite household. Among the contents Nelson identifies were numerous mahogany dining, breakfast and dressing tables; six large bedsteads with curtains; ten paintings; more than seventy-five framed prints; a billiard table; silver; and a chamber organ. The kitchen inventory included specialized cookware, while the stores contained large quantities of wine, ale, foodstuffs, textiles, and household supplies.

This is not the inventory one would expect from an abandoned building project. While there remains room for the possibility that portions of the wider complex were unfinished, the evidence strongly suggests that MacLeod's principal house was occupied and functioning before his death.

Then the Castle Appears on the Map

The documentary trail continues after MacLeod died. Nelson identifies the exact site on Archibald Campbell's Survey of the South Coast of Jamaica, prepared during Campbell's period in Jamaica in the early 1780s, where a house is marked and labeled "Colbeck." According to Nelson, the survey depicts it as a square house at the location. This is especially significant when compared with the earlier maps: before MacLeod's acquisition, no great house appears at the location, but after his ownership and the period in which Nelson dates construction, a substantial house does. The chronology is beginning to close.

1789: “Colbeck Castle”

The final piece may be the most striking. The National Library of Jamaica states that “the earliest known record of this mysterious building dates from 1896.” Yet the Morning Star of June 2, 1789 provides a much earlier reference. In an article discussing accommodation for British troops in Jamaica, the building is explicitly identified as “Colbeck Castle.” This pushes the documented use of the name back by more than a century.

The Morning Star article urged the British government to purchase Colbeck Castle rather than build new barracks for the troops. The writer claimed that the castle had cost its “present worthy proprietor” upwards of £70,000 sterling and suggested that it might be obtained for about half that amount. The £70,000 figure should be treated cautiously because it is a contemporary newspaper claim, not a surviving construction account. More important for the history of the building is that by 1789 it was already publicly known as “Colbeck Castle” and was considered substantial enough to accommodate British troops.

There is also important architectural evidence that predates Nelson's investigation. In April 1987, eleven years before Nelson first visited Colbeck, architectural writer Douglas Blain went to the ruins with British conservationist Marcus Binney. Blain later described a building that had progressed far beyond the stage of an unfinished masonry shell. He identified an internal staircase leading to the principal floor, a large hall that had once been partly paneled, a fireplace and chimney, an adjoining parlor or dining room, and probable bedrooms in the corner towers. Outside the main house, he found a substantial detached kitchen and an unusually elaborate water system in which rainwater from the roof was carried through underground vaulted drains to the surrounding pavilions.

Blain also recorded evidence of domestic facilities that suggest the complex had been designed for practical use, including latrines and a large plastered bath. None of this proves that John MacLeod and his household actually lived in the castle. But Blain's observations provide independent physical evidence that Colbeck was not simply abandoned as an unfinished stone structure. Significant interior finishing and domestic infrastructure had been installed before the building fell into ruin.

A Documentary Sequence Emerges

The evidence can now be arranged in a remarkably coherent order.

• Before 1749: maps that identify important houses do not show a major residence at the site.
• November 1749: John MacLeod purchases Colbeck. Improvements are mentioned elsewhere in the transaction but apparently not at Colbeck.
• 1754: a contemporary Jamaica Courant notice identifies John McLeod at Colbeck Plantation.
• Early 1760s: Nelson dates construction of the present castle to this period on documentary, cartographic and physical evidence.
• 1762: MacLeod seeks heraldic recognition as representative of a branch of the MacLeods of Lewis.
• 1775: MacLeod dies. His will refers to his mansion house and his probate inventory describes an extensively furnished elite residence.
• Early 1780s: Campbell's survey marks the substantial house at Colbeck.
• 1789: the Morning Star refers explicitly to “Colbeck Castle.”

No single item proves the entire case, but together, they are difficult to explain under the traditional 1680 interpretation.

What About the Spanish Theory?

There is another possibility that deserves acknowledgment. Architect Patricia Elaine Green has proposed a much earlier origin for Colbeck Castle. In a 2022 article, she argues that the surviving building began as a Spanish fortified house associated with Pedro de Mazuelo, which she dates to about 1520. Green also places an early settlement she calls “La Villa” in the area by about 1519. This chronology differs significantly from the more widely accepted history of Villa de la Vega, which dates its establishment as Jamaica’s new Spanish capital to 1534. Her proposal should therefore be understood as a competing interpretation rather than an established account of the site’s early history. The wider Colbeck area unquestionably has a history predating the English conquest, as a 2007 archaeological assessment by the Jamaica National Heritage Trust recovered Taíno, Spanish, Afro-Jamaican, and later English-period material from parts of the surrounding development area.

But an important distinction must be made: evidence of Spanish activity on the landscape does not by itself establish that the surviving walls of Colbeck Castle are Spanish. At present, the MacLeod hypothesis has a documentary sequence tied specifically to the estate and mansion—the 1749 acquisition, the absence of an earlier great seat on relevant maps, the later mansion-house and inventory, the early-1780s map, and the 1789 reference. The Spanish hypothesis would need to explain that sequence and demonstrate that masonry surviving in the present structure can be securely dated to the sixteenth-century Spanish period.

It should not be dismissed, and it should be tested, but on the evidence currently available, the MacLeod interpretation is considerably stronger.

The Name May Have Hidden the Builder

The simplest explanation for the long confusion may also be the most human. John Colbeck unquestionably gave his name to the estate, and long after his death, the property was still Colbeck or Colbecks. When a monumental ruin stood there generations later and became known as Colbeck Castle, it was natural to assume that the man whose name it carried must have built it.

But place names can outlive owners by centuries. The surviving building does not have to date from Colonel Colbeck's lifetime simply because it stands on Colbeck's former land; indeed, the evidence increasingly suggests that it does not.

So Who Built Colbeck Castle?

At this stage, the most defensible answer is that John MacLeod probably commissioned the surviving Colbeck Castle in the early 1760s, on an estate that had carried Colonel John Colbeck's name since the seventeenth century. That conclusion is not based simply on architectural style, but rests instead on several independent kinds of evidence pointing in the same direction.

• The great house is absent from maps before MacLeod acquired Colbeck.
• The 1749 transaction apparently records no great improvement there.
• MacLeod is demonstrably at Colbeck by 1754.
• Architectural historian Louis P. Nelson's examination of the building places its construction program in the middle decades of the eighteenth century.
• MacLeod's 1775 will identifies a mansion house.
• His probate inventory describes the furnishings and service equipment of an occupied and exceptionally wealthy residence.
• The house appears on Campbell's early-1780s survey.
• And by 1789, a London newspaper was calling it Colbeck Castle.

That is an evidentiary chain the traditional story has never had. It does not yet tell us who drew the plans, who supervised construction, which masons and carpenters built it, exactly when work began, or whether any earlier building was incorporated into the complex—those questions remain open.

But perhaps the central mystery of Colbeck Castle has been framed incorrectly for more than a century. The question may no longer be whether Colonel John Colbeck built a castle around 1680, as the evidence increasingly points elsewhere.

The more interesting question is now: what happened at Colbeck after John MacLeod acquired the estate in 1749 that produced one of the most extraordinary buildings ever constructed in Jamaica? That is a question the surviving records may finally allow us to answer.
