The Gould-Guggenheim Estate, or the Hempstead House, is a historic mansion located in Port Washington, New York. This 216 acre (87 hectare) estate was built in 1909 and includes two buildings that look more like castles. The bigger house is as grand as grand can get, stretching across three floors and consisting of forty rooms. The interiors of the houses are even more extravagant than the exteriors, with lavish furnishings made of expensive timber.
