Brimstone Hill Fortress National Park

Brimstone Hill Fortress National Park is an outstanding, well-preserved example of 17th- and 18th-century military architecture in a Caribbean context. Designed by the British and built by African slave labour, the fortress is testimony to European colonial expansion, the African slave trade and the emergence of new societies in the Caribbean.

Brimstone Hill is an outstanding British fortress, built by slave labour to exact standards during a peak period of European colonial expansion in the Caribbean. Criterion (iv): Because of its strategic layout and construction, Brimstone Hill Fortress is an exceptional and well preserved example of 17th and 18th century British military architecture.

The Brimstone Hill Fortress is of historical, cultural and architectural significance, a monument to the ingenuity of the British military engineers who designed it and supervised its construction and to the skill, strength and endurance of the African slaves who built and maintained it. In some of its architectural features, notably the Citadel, are expressed elements of different stages of fortress design; it is an embodiment of European imperialism, and the emergence of a distinctive Caribbean culture. It is indicative of the competition for power and wealth at a crucial stage in world history, and it provides a medium by and through which the geology, ecology and history of the Caribbean can be understood. As managed by a competent local organization on behalf of the people of a young nation, the majority of whose citizens are descended from former slaves, it is a symbol of a colonized African people and of the integrity of Caribbean culture, and as such it can be an inspiration to other young nations in a post-colonial era.

Known as Liamuiga (Fertile Island) to the native Amerindians, Saint Kitts was the first Caribbean island to be permanently settled by both the English (in 1623) and the French (1625), who shared it between 1627 and 1713, when it came under sole English control through the Treaty of Utrecht. Known as the 'Mother Island', it provided the model and springboard for English and French colonization in the Caribbean. African slaves were brought in from the earliest years of European settlement, and it was on Saint Kitts and the other early colonies that the plantation system, based on sugar production and slavery, had its roots.

Because of its reconstructed and very formidable defences, Saint Kitts became known as the 'Gibraltar of the Caribbean'. It successfully drove off an attack by the French Navy in 1806. From that time onwards the British Navy was able to ensure the security of its island colonies in the Caribbean. The fortress was abandoned as a result of British defence cuts in 1853. The wooden buildings were auctioned and dismantled and masonry buildings were plundered for their cut stone; natural vegetation progressively took over.

Brimstone Hill is a twin-peaked upthrust of volcanic rock 230 m high, clad with limestone over much of its surface. It is covered with scrub, with patches of bare rock in places; the more sheltered areas and ravines are covered with large trees and dense undergrowth. The fortress was constructed to protect part of the coast of the island settled by the English against attack from the sea, and also to provide a place of refuge in case of invasion, until the Royal Navy could secure the surrounding waters and force the surrender of the invading land army. As such it is strategically distinct from the Spanish fortresses.

The principal structures, on different levels on the upper third of the hill, were in dressed stone (basalt) blocks, with a rubble core. The local limestone was used as a decorative element for quoins and for facing round doorways and embrasures. On entering the fortress, the first structure is the Barrier Redoubt, with defensive walls and a small casemate that served as a guardroom and powder magazine. Next comes the North-West Work, which incorporates the stout Magazine Bastion with its associated water catchments and cistern. This in linked by a curtain wall to the South-East Work, the main feature of which is the Orillon Bastion, the counterpart to the Magazine Bastion. A prominent feature here is the bombproof Ordnance Storehouse. The hospital was located within this bastion, but only its foundations survive. Outside the wall is a small cemetery with tombstones. Behind the defensive line is the massive Prince of Wales Bastion.

There is an impressive row of colonnaded basements of the Infantry Officers' Quarters nearby. This faces the Grand Water Catchment System, consisting of paved catchments, three underground water cisterns, and an open tank. No more than some ruined walls of the Artillery Officers' Quarters survive, but the kitchen has been restored. In the Commissariat Yard, the Warrant Officers' Quarters and the Commissariat Storehouse have been reconstructed. The system of walls known as the North-East Work has several barrack blocks behind it, but they are still unrestored. The heart of the fortress is Fort George, the massive masonry structure on one of the twin peaks that dominate the complex, still in an excellent state of repair. It is the earliest surviving British example of the type of fortification known as the 'polygonal system', and one of the finest examples known anywhere in the world.
