The stone walls of Skansin sit on a low hill above the eastern side of the harbour, a ten-minute walk from Tinganes. The fortress has been rebuilt several times — most recently in the 18th century — and now functions as an open-air park rather than a serious defensive position.
Two old cannons and a lighthouse still stand within the walls, and the views over the harbour and the strait towards Nólsoy are among the best in town. Free entry, always open.
