Two lighthouses are on the south end of Nólsoy. The smaller, placed on Borðutanga, can be seen from Tórshavn. The larger lighthouse was built in 1893 on a place called Tumbin. This lighthouse is one of the most powerful in the world, and the light can be seen far out into the ocean. Close to the lighthouse is a row of houses, where the lighthouse keepers and there families lived. During the second world war British soldier dwelled on Borðan, and remains from their buildings are still to be seen.
