Few historic houses have stranger surroundings—encircled by gigantic factory sheds. Shortly after 1800, Clyde Mansion was home to Swedish painter Adolph-Ulrich Wertmüller, who charged the public admission to see his racy painting, Danae (1787). An old photograph shows three sections to the house: the original stone building with heavy, white shutters; a brick wing; and a small board-and-batten extension to that, with jigsaw trim. Claymont Historical Society hopes to save the derelict building, which stands on the grounds of the former Worth steel mill. Nearby is the stone-arched Amtrak Bridge over Naamans Creek (1901). That tributary, now despoiled, was once a fishing place for Indians.
