OTHER
British Base ‘Y’ is designated as Historic Site and Monument No. 63. It sits on a small peninsula at the northwestern end of the island overlooking Sally Cove. It is noteworthy as a relatively unaltered and well equipped British scientific base of the late 1950s, providing a time capsule of life and science of the time. It was occupied continuously from March 1955 to August 1960, and re-opened for a 4 month period in 1969. In addition to the base building, there is also a balloon shed, pup pens, an emergency store, two pram dinghies and a winch. ‘Blaiklock’, the refuge hut located several miles away, is considered an integral part of the base.
