This building was built in 1813 as the shore station for the Bell Rock lighthouse, erected by Robert Stevenson. It consisted of the lightkeeper’s houses, a signal tower, sea wall, storehouses and accommodation for the master and crew of the attending vessel. In the 1950s, when the lightkeepers left for Granton, the tower became council houses and remained so until the 1970s when it became Arbroath's museum, where visitors can see the massive lens of the last manual lamp, and hear the keeper describe a typical shift.
