A Historic Site or Monument (HSM) is a protected location of historic interest on the continent of Antarctica, or on its adjacent islands. The list of historic sites was first drawn up in 1972,[1] and has since expanded to cover 95 sites, with the most recent listed in 2021.[2] Five sites have been removed from the list for various reasons.

The plaque at the foot of the monument commemorates the signatories of the Antarctic Treaty. This Monument has 4 plaques in the official languages of the Antarctic Treaty. The plaques were installed in February 2011 and read as follows: "This historic monument, dedicated to the memory of the signatories of the Antarctic Treaty, Washington D.C., 1959, is also a reminder of the legacy of the First and Second International Polar Years (1882–1883 and 1932–1933) and of the International Geophysical Year (1957–1958) that preceded the Antarctic Treaty, and recalls the heritage of International Cooperation that led to the International Polar Year 2007–2008." This monument was designed and built by the American Joseph W. Pearson, who offered it to Chile. It was unveiled in 1999, on the occasion of the 40th anniversary of the signature of the Antarctic Treaty.
Base "W" is situated on a narrow isthmus at the northern end of Detaille Island, Lallemand Fjord, Loubet Coast. The site consists of a hut and a range of associated structures and outbuildings including a small emergency storage building, bitch and pup pens, anemometer tower and two standard tubular steel radio masts (one to the south west of the main hut and the other to the east). Base "W" was established in 1956 as a British science base primarily for survey, geology and meteorology and to contribute to the IGY in 1957. As a relatively unaltered base from the late 1950s, Base "W" provides an important reminder of the science and living conditions that existed when the Antarctic Treaty was signed 50 years ago.
The site consists of a well-preserved hut and the scientific equipment and other artefacts inside it. It is located at Damoy Point on Dorian Bay, Wiencke Island, Palmer Archipelago. The hut was erected in 1973 and used for a number of years as a British summer air facility and transit station for scientific personnel. It was last occupied in 1993.

It is approximately half way up the west side of Observation Hill. The plaque text details achievements of PM-3A, Antarctica's first nuclear power plant.
The No.1 Building, built in 1985 with a total floor space of 175 square meters, is located at the centre of the Chinese Antarctic Great Wall Station which is situated in Fildes Peninsula, King George Island, South Shetlands, West Antarctica. The Building marked the commencement of China devoting to Antarctic research in the 1980s, and thus it is of great significance in commemorating China's Antarctic expedition.
Location of the first permanently occupied German Antarctic research station "Georg Forster" at the Schirmacher Oasis, Dronning Maud Land.
The original site is situated by the Schirmacher Oasis and marked by a commemorative bronze plaque with the label in German language: Antarktisstation Georg Forster 70° 46’ 39’’ S 11° 51’ 03’’ E von 1976 bis 1996 The plaque is well preserved and affixed to a rock wall at the southern edge of the location. This Antarctic research station was opened on 21 April 1976 and closed down in 1993. The entire site has been completely cleaned up after the dismantling of the station was successfully terminated on 12 February 1996. The site is located about 1.5 km east of the current Russian Antarctic research station Novolazarevskaya.
The drilling complex building was constructed in the summer season of 1983–84. Under the leadership of Professor Boris Kudryashov, ancient mainland ice samples were obtained.
Terra Nova Expedition 1910–12, Upper "Summit Camp" used during survey of Mount Erebus in December 1912.
Camp Site location includes part of a circle of rocks, which were likely used to weight the tent valences. The camp site was used by a science party on Captain Scott’s Terra Nova Expedition, who undertook mapping and collected geological specimens on Mount Erebus in December 1912.
Terra Nova Expedition 1910–12, Lower "Camp E" Site used during survey of Mount Erebus in December 1912.
Camp Site location consists of a slightly elevated area of gravel and includes some aligned rocks, which may have been used to weight the tent valences. The camp site was used by a science party on Captain Scott’s Terra Nova Expedition, who undertook mapping and collected geological specimens on Mount Erebus in December 1912
Lame Dog Hut at the Bulgarian base St. Kliment Ohridski, Livingston Island.
The Lame Dog Hut was erected in April 1988, and had been the main building of St. Kliment Ohridski base until 1998. It is presently the oldest preserved building on Livingston Island, used as radio shack and post office, and hosting a museum exhibition of associated artefacts from the early Bulgarian science and logistic operations in Antarctica.
Oversnow heavy tractor "Kharkovchanka" that was used in Antarctica from 1959 to 2010.
The oversnow heavy tractor "Kharkovchanka" was designed and produced at the Malyshev Transport Machine-Building Plant in Kharkov specially for organizing inland sledge-tractor traverses in Antarctica. This was the first non-serial transport vehicle of the Soviet machine-building produced exclusively for operations in Antarctica. This tractor was not used outside Antarctica. Thus, the STT "Kharkovchanka" is a unique historical example of engineering-technical developments made for exploration of Antarctica.
Endurance, Wreck of the vessel owned and used by Sir Ernest Shackleton during his 1914-15 Trans-Antarctic Expedition
Wreck of the vessel Endurance, including all artefacts contained within or formerly contained within the ship, which may be lying on the seabed in or near the wreck within a 150m radius. This includes all fixtures and fittings associated with the ship, including ship’s wheel, bell, etc. The designation also includes all items of personal possessions left on the ship by the ship’s company at the time of its sinking. The exact location of the wreck is unknown as the ship floated in the pack ice for some distance. Location records made by Frank Worsley, Shackleton’s skipper and master navigator, give precise coordinates of the location of sinking of the ship but these have not been verified since 1915. We know the wreck is somewhere on the seabed in the Weddell Sea. It is proposed to designate the wreck and all artefacts contained within or formerly contained within the ship, which may be lying on the seabed in or near the wreck.
The site consists of a rock cairn installed in 1892 by Norwegian Capt. Carl Anton Larsen during the first land-exploration of the area around the current location of Argentina's Marambio Station, where the first Antarctic fossil discoveries were made. The cairn used to have an attached wooden pole (2m high and 5cm diameter) of which nothing remains. Location: northeast of the Argentine Station Marambio, Antarctic Peninsula.
