Chatham is one of the Medway towns located within the Medway unitary authority, in North Kent, in South East England.
Chatham Royal Dockyard closed in 1984, but major naval buildings remain as the focus for a flourishing tourist industry. Following closure, part of the site became a commercial port, other parts were redeveloped for business and residential use, and part became the Chatham Historic Dockyard museum, which features the submarine HMS Ocelot among a good many other attractions.
Chatham also has military connections; several Army barracks were located here, together with 19th-century forts which provided a defensive shield for the dockyard. Brompton Barracks, located in the town, remains the headquarters of the Corps of Royal Engineers.
