Tower Hill Memorial

The Tower Hill Memorial is a pair of Commonwealth War Graves Commission memorials in Trinity Square Gardens, on Tower Hill in London, England. The memorials, one for the First World War and one for the Second, commemorate civilian, merchant seafarers and fishermen who were killed as a result of enemy action and have no known grave. The first, the Mercantile Marine War Memorial, was designed by Sir Edwin Lutyens and unveiled in 1928; the second, the Merchant Seamen's Memorial, was designed by Sir Edward Maufe and unveiled in 1955. A third memorial, commemorating merchant seamen who were killed in the 1982 Falklands War, was added to the site in 2005.

The first memorial was commissioned in light of the heavy losses sustained by merchant shipping in the First World War—more than 17,000 people died and some 3,300 British and Empire-registered commercial vessels sunk as a result of enemy action.
