From collection Place
"The Seaside Hall building, which served as a museum of the island's past, was sold in 2007, and was moved to a new location by the new owners. The museum's collection was removed from the building in the summer of 2007 Many of the articles were moved to the Olde Atlantic Schoolhouse, which served as the library. It was destroyed in a fire in July, 2008, along with all contents. The Swan's Island Historical Society has begun collecting artifacts of significant historical value in an effort to establish a new collection.
