The Lame Dog Hut (Bulgarian: Куцото куче, romanized: Kutsoto Kuche, IPA: [ˈkut͡soto ˈkut͡ʃɛ]) is a building in St. Kliment Ohridski Base on Livingston Island in the South Shetland Islands, Antarctica. Presently the oldest preserved building on the island, since October 2012 the hut has been hosting the Livingston Island Museum, a branch of the National Museum of History in Sofia. It was the first permanent building established by Bulgaria in Antarctica, which laid the foundations for Bulgaria's systematic scientific research in the Livingston Island area under the Antarctic Treaty System. The building is a designated Historic Site or Monument of Antarctica.

The hut is located at 62°38′29″S 60°21′53″W / 62.64139°S 60.36472°W / -62.64139; -60.36472, which is 70 m south by east of the main building of St. Kliment Ohridski base and 200 m from the coast of South Bay, at elevation 15.5 m. It stands between two branches of the melt-water Rezovski Creek, surmounted by Pesyakov Hill and Sinemorets Hill, and overlooking Grand Lagoon.

The Lame Dog Hut is a Bulgarian-made 6 by 3.5 m sandwich panel structure (metal face sheets, polyurethane foam core) with a mess area and accommodation capacity for 6 persons. It has a particular technical and architectural value in its materials, design and method of construction, namely in the ingenuity and skills demonstrated by the Bulgarian scientists and technical personnel who, by using material at hand, converted what was, basically, a standard dwelling container designed for use in the then Bulgarian logging industry in northern Russia, into a cozy and hospitable Antarctic facility much favoured by people from various nations visiting or working at the Bulgarian base. The experience gained during the construction and maintenance of the Lame Dog Hut was instrumental in the subsequent expansion of the Bulgarian base.^[1]

The name Lame Dog Hut dates to around 1999, when the hut was found bouncing in the wind with its support legs damaged during the winter. This somewhat peculiar name became established both in common usage and also in the Bulgarian Antarctic Institute’s official documentation.^[2]

The prefabricated hut made in Pazardzhik was assembled on Livingston Island during the First Bulgarian Antarctic Expedition by the team of Zlatil Vergilov, Asen Chakarov, Stefan Kaloyanov and Nikolay Mihnevski from 26 to 28 April 1988, with the logistic support of the Soviet Research Ship Mikhail Somov under Captain Feliks Pesyakov. It was renovated and, together with the adjacent Russian Hut, a small storehouse, commissioned as Antarctic base St. Kliment Ohridski (often shortened by non-Bulgarians to Ohridski base) on 11 December 1993. It remained the base's only dwelling facility (with tents used when additional accommodation was necessary) until a new main building was completed in 1998. Occupied during all summer seasons since 1993, the hut has proved most suitable under local conditions. It has also been used as a radio shack and post office (Post Office Antarctica 1090 maintained by Bulgarian Posts Plc) since 1994.^[3][2]

Since October 2012 the Lame Dog Hut has been hosting a museum exhibition of associated artefacts from the early Bulgarian science and logistic operations in Antarctica, designated as Livingston Island Museum – a branch of the National Museum of History in Sofia.^[2][4]

Since June 2015 the hut has been designated a Historic Site or Monument of Antarctica (HSM 91, effective 31 October 2015).^[5] As the oldest preserved building on Livingston Island (since 2009, when the old buildings of the nearby Spanish base Juan Carlos I were removed and replaced by new ones), the hut and its associated artefacts are considered part of the cultural and historic heritage of the island and Antarctica.^[1][6] Another Historic Site or Monument on Livingston Island is the San Telmo Cairn (HSM 59) at Cape Shirreff, which commemorates the 644 officers, soldiers and seamen lost when the Spanish warship San Telmo sank nearby in September 1819.^[5]
