Pictured is the Rock Island, Wisconsin boathouse in Door County.
Most just call the boathouse the Rock Island boathouse. It does have a name. The Chester Thordarson's boathouse.
The boathouse was built in 1910 by a wealthy inventor Chester Thordarson. He purchased 775 acres of the island. 30 acres on the southwest side of the island were cleared in 1920 and Thordarson began construction of a summer estate. His large boathouse, which is decorated in with characters from the Norse Runic alphabet, is open to the public
