The Forts of Jamaica
An island taken by force expects to be taken again. For a century and a half after 1655 the English ringed Jamaica’s coast with gun platforms, built of local stone by enslaved hands and paid for out of the public purse in Spanish Town. Around twenty stood at the peak. Eighteen are on the national register. This is all of them.
The Economics of Defence

Who paid, and who built
Since the English captured Jamaica from the Spanish in 1655, fortification was urgent. The threat of invasion was constant, and the priority was Port Royal — then the island’s main naval and commercial hub, and for a time the largest city in the Caribbean.
The money came from the House of Assembly in Spanish Town. Through the relatively peaceful eighteenth century roughly £1,250 a year was set aside for forts out of a total budget of about £7,000. When the threat sharpened the vote rose steeply: £9,000 in 1746, and as much as £20,000 towards the end of the century as fear of French invasion grew.
A special committee of the Assembly managed the funds and awarded contracts to local builders. The material was durable and mostly local — stone from Jamaican quarries, occasionally supplemented with stone shipped in from Bath in England.
The skilled labour was largely provided by enslaved people. Up to five hundred worked a single fort at a time, drawn from nearby estates or from the prisons.
That last sentence is the one to sit with. These walls are usually described in terms of guns, garrisons and governors. They were built by people who had no stake whatsoever in what the guns were pointing at.
Placement followed the ground. Forts went on high land where it was available, to command the coastline; where it was not, they sat flat and close to the shore, sized to the number of guns the position needed. At the height of the programme around twenty forts formed a working network of outposts around the island.

Port Royal, Kingston
Fort Charles
1656 · oldest in Jamaica
Open to the publicThe first fort built in Port Royal, and the oldest in Jamaica. It went up in the late 1650s under Cromwell’s protectorate and was originally called Fort Cromwell; in 1662 it was renamed for Charles II, restored to the throne two years earlier. The fort was altered repeatedly between 1656 and 1670.
Its armament tells the story of the island’s anxiety. Ten guns at the start, thirty-six by 1667, and one hundred and four by 1765, with a garrison to match. It is built in the shape of a ship, and when new it had water on three sides; the ground around it has silted up since, and it now sits inland.
Of the six forts at Port Royal, Fort Charles was the only one to survive the earthquake of 1692. Damaged but standing, it was reconstructed in 1699 by Colonel Christian Lilly, chief engineer of Jamaica. Horatio Nelson walked its quarterdeck, and a plaque there still records it.

Kingston
Port Royal Forts
1650s onward · six forts
Heritage townPort Royal was called the richest and wickedest city in the world. Founded in the 1650s by the first British settlers, the town grew up around Fort Charles and filled with traders, shopkeepers, innkeepers, soldiers, buccaneers and pirates — along with carpenters, bricklayers, tailors, goldsmiths and silversmiths. By 1690 it held between eight and ten thousand permanent inhabitants, some houses standing three or four storeys high, with bars, taverns, restaurants, coffee houses and brothels.
Six forts defended it. Five were destroyed a few minutes before midday on Tuesday 7 June 1692, when an earthquake struck and a tidal wave swept the harbour, carrying one ship into the middle of the town.
The Giddy House is the other survival worth the trip: built in 1888 as the Royal Artillery store for the Victoria Battery, it was shoved to a 45-degree angle by the 1907 earthquake. Walking into it produces exactly the sensation the name promises.

St Catherine
Fort Augusta
18th century
Now a prisonFort Augusta sits on the seaward side between Port Henderson and Passage Fort, covering the western approach to Kingston Harbour — the other jaw of the trap that Fort Charles closed from the east.
It has had the strangest afterlife of any fort on the register. The site now operates as the Fort Augusta Adult Correctional Centre, Jamaica’s women’s prison, which makes it one of the few eighteenth-century fortifications anywhere still in continuous government use for confinement of one kind or another.

St Andrew
Fort Nugent
Martello tower, c.1806
RuinAll that remains of Fort Nugent is its Martello tower, built around 1806 — the squat, thick-walled circular design the British adopted across the empire during the Napoleonic wars.
The first fortification here is said to have been raised by a Spanish slave agent, James Castillo, and later reinforced by Sir George Nugent, governor from 1801 to 1806 and commander-in-chief of Jamaica, who gave the fort its name.

Kingston
Rockfort
18th century
Mineral bathRockfort stands beside the Jamaica Cement Company works, facing Kingston harbour at the eastern entrance to the city — the last hard point before the road runs out towards Bull Bay.
Its second life is unexpectedly gentle. The Rockfort Mineral Bath operates on the site, fed by a spring, and the Heritage Trust reopened it after a round of major upgrades. A gun position turned into a place people go to soak.

St Catherine
Fort Small
1782
RuinBuilt in 1782 to protect the bay between Port Henderson and the Hellshire Hills — the stretch of coast west of the harbour mouth where a landing force could have come ashore and marched on Spanish Town.
The date matters: 1782 was the year of the Battle of the Saintes, and the Caribbean was thick with French and Spanish fleets. Jamaica was building fast.

Lucea, Hanover
Fort Charlotte
mid-18th century
Standing · visitableBuilt by the British in the middle of the eighteenth century to defend the north-north-westerly corner of the island, during the reign of George III and named for his consort, Queen Charlotte.
It is the best-documented fort on the register. The barrack could house fifty men. There were twenty-three embrasures cut for twenty-three guns, though only twenty were ever mounted. During the Napoleonic wars the armament was judged insufficient to hold the harbour, so in 1807 three 24-pounders on traversing carriages were installed on the seaward side.
The structure is rectangular cut stone with several openings towards the sea, and inside you can still see the remains of the circular bases the guns rotated on — the physical evidence of a field of fire.

Montego Bay, St James
Fort Montego
18th century
In the townBy the record it appeared to be a large fort, housing four 12-pounder guns to cover the bay that would become Jamaica’s second city and its tourism capital.
It now sits inside modern Montego Bay, a few minutes from the Hip Strip — one of the easiest forts on the island to walk up to.

Westmoreland
Savanna-la-mar Fort
18th century · unfinished
RuinThe fort at Savanna-la-mar has no name on record. It was never finished, and the Heritage Trust notes simply that it seems to have gone without one — so it has been called the fort ever since.
An unfinished, unnamed fort is its own kind of historical document: money voted, work begun, threat receded or funds ran out. It is the only entry on the register without a glossary page of its own.

Rio Bueno, Trelawny
Fort Dundas
1778
RuinFort Dundas stands behind the Rio Bueno Primary School, carrying the date 1778 — built as the American War of Independence widened into a global conflict and the French entered on the rebel side.
Rio Bueno is a deep natural harbour on the Trelawny coast, which is why it was worth defending and why some hold it to be Columbus’s actual first landing point on the island.

St Ann’s Bay, St Ann
St Ann’s Bay Fort
c.1750
RuinErected about 1750 at St Ann’s Bay, covering the anchorage beside the site of Sevilla la Nueva — the first Spanish capital, abandoned nearly a century before the fort was raised over the same water.

Ocho Rios, St Ann
Ocho Rios Fort
late 17th c. · rebuilt
Roadside · visitableBuilt in the late seventeenth century and strengthened in 1780, like so many others, when French attack was feared. It sits right on the main road through Ocho Rios.
It is one of the few Jamaican forts with a recorded success. In 1795 an enemy vessel approaching Ocho Rios thought better of it and diverted to Mammee Bay instead — the fort did its job without firing on the town.
Rebuilt by Reynolds Jamaica, it holds two of the original guns that defended the coast at Mammee Bay.

Oracabessa, St Mary
Fort Oracabessa
War of Trade era
RuinBuilt during the War of Trade — the commercial conflict with Spain that began over a severed ear and ran into the wider European wars of the 1740s. Jamaica’s forts were, at bottom, insurance on the sugar trade.
Oracabessa is better known now as the stretch of coast where Ian Fleming built Goldeneye and wrote the Bond novels.

Port Maria, St Mary
Fort Haldane
1759
RuinErected at Port Maria in 1759 and named after General George Haldane, then Governor of Jamaica, with its guns strategically positioned over the bay.
Within a year it was on the wrong end of history. Tacky’s Revolt broke out in St Mary at Easter 1760, and the rebels are recorded as taking the fort’s store for arms and powder before moving inland — one of the largest slave uprisings in the eighteenth-century Caribbean, and it began by capturing a fort built to repel the French.
Little survives. The remains can be identified at Gray’s Charity, a home for the elderly in Port Maria.

Port Antonio, Portland
Fort George
18th century
School groundsFort George stands on the Titchfield Peninsula in Port Antonio, the finger of land that divides the town’s twin harbours — as commanding a defensive position as exists on the island.
The peninsula is a heritage district in its own right, and the fort’s remains now sit within the grounds of Titchfield High School. Generations of Portland schoolchildren have taken their break beside eighteenth-century gun walls.

Morant Bay, St Thomas
Morant Bay Fort
probably 1758
RuinProbably built in 1758 and designed for nine guns, covering the bay on the island’s south-eastern shoulder.
Morant Bay’s place in Jamaican history came a century later, with the rebellion of 1865 led by Paul Bogle that ended in the execution of Bogle and George William Gordon — and, eventually, the end of the Assembly that had voted the money for forts like this one.

Morant Point, St Thomas
Fort Lindsay
1745
RuinBuilt in 1745 at Morant Point, near Old Pera, directly opposite Fort William — the two together closing the entrance to Port Morant harbour from either side. It mounted nine guns and had a magazine and barracks attached.
Its last chapter is unusual. After the First World War the government rented out the land near the barracks and used the income to support St Thomas’s returning war veterans — a fort paying a pension.

Port Morant, St Thomas
Fort William
from 1675
RuinAs early as 1675 Port Morant had a platform mounting five guns to defend its harbour — among the earliest fortifications on the island outside Port Royal, and a sign of how valuable the eastern sugar country already was.
The fort stood at Prospect, opposite Fort Lindsay, guarding the western side of the harbour entrance. It is in ruins now.

Who actually built the fortsSeven Minutes
7 June 1692: five of six forts gone
A few minutes before midday on a Tuesday, the richest city in the Caribbean fell into the sea.
Port Royal had been founded in the 1650s on a sand spit at the mouth of what is now Kingston Harbour. It grew around Fort Charles into something no other English settlement in the Americas matched: eight to ten thousand people by 1690, houses of three and four storeys, and an economy built on the plunder that buccaneers brought back into a port willing to bank it.
The ground it stood on was the problem. Sand and gravel, saturated with water, will liquefy under seismic shaking, and on 7 June 1692 that is what happened. A large part of the town slid beneath the harbour. A tidal wave swept the anchorage and carried a ship into the middle of the streets.
Five of the six forts were destroyed. Only Fort Charles survived, damaged, and it was reconstructed seven years later by Colonel Christian Lilly, the island’s chief engineer. Kingston was founded across the water shortly afterwards, and the centre of gravity never returned.
Two centuries later the ground moved again. The 1907 earthquake tipped the Royal Artillery store at the Victoria Battery onto a permanent 45-degree lean, and left Jamaica with the Giddy House — a building that is now a tourist attraction precisely because it is broken.
