 The Norwegian Polar Institute decided to establish a summer station. This was built during the summer of 1989 and 1990, resulting in a 100-square-meter (1,100 sq ft) building with room for eight people. Construction required 300 tonnes (300 long tons; 330 short tons) of materials to be hauled from the coast and the station was officially opened on 17 February 1990. The station took its name from the surrounding jagged mountains, which resemble trolls of Norse mythology. The first overwintering occurred in 2000, when a South Pole expedition used the camp as a base.
