The Hackness Martello Tower and Battery were built in 1813-14 to protect British convoys during the Napoleonic Wars, with French and American warships attacking merchant shipping using the Pentland Firth.

Although the sites didn’t see any enemy action, even when they were brought back into use in the 1860s, they still offer a fascinating glimpse into military life more than 200 years ago.

The Martello Tower, one of only three surviving in Scotland, offers views over Scapa Flow, Orkney's famous naval anchorage during both world wars. The battery gives visitors the chance to experience barracks life and features furniture and other items of military memorabilia.
