Among the notable structures in the town are the three forts built by the Swedes for defense purposes. One of these forts, known as Fort Oscar (formerly Gustav Adolph), which overlooks the sea is located on the far side of La Pointe. However, the ruins have been replaced by a modern military building which now houses the local gendarmerie. The other fort known as Fort Karl now presents a very few ruins. The third fort built by the Swedes is the Fort Gustav, which is also seen in ruins strewn around the weather station and the Light House. The fort built in 1787 over a hill slope has ruins of ramparts, guardhouse, munitions depot, wood-burning oven and so forth.
