In the mid–19th century when Nantucket was a wealthy boomtown because of the success of sea captains in the whaling industry, there sprang up luxe houses like this Greek Revival beauty on Upper Main Street. Docents give a good feeling for the time period as they give tours around this 1845 mansion, a twin to the house next door. Whaling merchant William Hadwen hired a builder who specialized in intricate carving the construct the house’s five-bayed facade, colossal pilasters and pedimented ionic portico. The house is a symbol of the wealth and prosperity of the island at that time. Inside is period furniture and outside are gardens maintained in period style. Please note that a pass to all of the island's historic sites is used for entry here.
