Key for the Martello Tower, Leith. Marked 'MARTELLO TOWER' / 'LEITH' on one side ''W D' and arrow on the other representing the ordnace mark of the War Department. The Martello Tower, which still stands within Leith Docks, was one of a series of coastal circular towers built around the coast to protect Britain from invasion during Napoleonic Wars with France. Built to protect the new docks at Leith, it was never used to defend it and became redundant after the Napoleonic Wars. On display at Trinity House, Leith.
