Fort Pitt is a Napoleonic era fort on the high ground of the boundary between Chatham and Rochester, Kent.
A fortification on the site was proposed as early as October 1779 by Hugh Debbieg, then Chief Engineer at Chatham. During April 1783 the land was purchased by the Board of Ordnance and 4.5 million bricks were deposited there in preparation for construction of Fort Pitt. (Nothing immediately followed, however, and the bricks were instead used for the rebuilding of the Lines).
Fort Pitt was finally built between June 1805 and April 1819. At that point, the Napoleonic Wars having ended, it ceased being manned as a defensive installation and instead became an important military hospital. From March 1824 to February 1857 it was the only General Military Hospital, as opposed to Regimental Military Hospital, in England, and, until the opening of Netley Hospital in 1863, it was considered the de facto Headquarters of the Army Medical Department. Fort Pitt Hospital closed in the 1920s, since then the surviving buildings have housed a girls' grammar school.
