SEASIDE HALL The Seaside Hall building, which served as a museum of the island's past, was sold in 2007, and will be moved to a new location by the new owners. The museum's collection was removed from the building in the summer of 2007. Seaside Hall was built in 1905 on the shore of Mackerel Cove by the Atlantic Improvement Association. The building was used by residents of Atlantic for recreational purposes, plays and dances. View photographs from Swan's Island's past.
