From 1994: Historic Sites in Antarctica
In 1994 the British Antarctic Survey (BAS), on behalf of the Foreign and Commonwealth Office (FCO) and UKAHT, carried out a conservation survey of several abandoned British bases on the Antarctic Peninsula. As a result, four bases – Port Lockroy, Argentine Islands (Wordie House), Horseshoe Island and Stonington Island – were designated as Historic Sites and Monuments (HSMs) under the Antarctic Treaty (respectively Nos. 61, 62, 63, 64). With funding from the FCO, in 1996 BAS restored Port Lockroy to its 1962 condition (when it closed). Since then it has operated during the summer months as a living museum and Post Office, run by BAS until UKAHT took over its management in 2006.
