The Mansion House is the historic home of the utopian Oneida Community (1848-1880). The 93,000 square ft. Mansion House is a National Historic Landmark where visitors can enjoy period rooms and interpretive exhibits in the museum, as well as programs, facility rentals, and overnight lodging. It is surrounded by 33 acres of landscaped lawns, gardens, trails and a historic golf course. The Community’s radical social practices, which included living and working communally and advocating for women’s equality, challenged contemporary ideas of family and gender roles in ways that are still relevant today. Their progressive philosophy is evident in the Mansion House itself, the design of which reflects their values and social organization. Today, the non-profit organization, the Oneida Community Mansion House (OCMH), tells the story of America’s most successful experimental community and the joint stock company that emerged after its breakup.
