The Swedish South Polar Expedition’s prefabricated black-walled hut, the Antarctic Peninsula’s oldest remaining building, is a protected historic site. This dwelling, in which five Swedish and one Argentine scientist spent an unplanned two years, sits on a fragile beach terrace easily eroded by footsteps. The 6m-by-8m hut contains three double bunks, a kitchen and a central living room. Two large metal signs in Spanish describe the site’s history, as do leaflets in English inside the hut.

　　Two angled wooden planks, original to the design, support the northeast wall.

　　The Argentine government, whose Marambio Station on Seymour Island is 21km northeast, maintains the hut. No more than five people are allowed in the hut at a time, with no visits between 7pm and 8am.

　　Behind the hut is a snowless ravine, where visitors can pluck fossils of clams and ammonites from the gravel to show to one another (but not take them!).
