Townsend Mansion

Cosmos Club

Almost completed rebuilt by heiress Mary Scott Townsend in 1899, the house features a Beaux Arts, Louis XVI French-inspired design. Townsend lived there until she died in 1931. For a period of time before World War II, Sumner Welles, the son-in-law of Mary Scott Townsend and Franklin D. Roosevelt's Under Secretary of State, lived in the Townsend Mansion. The Cosmos Club, a private social club, bought the house in 1950, and continues to occupy the mansion.

Anderson House
Society of the Cincinnati headquarters and museum
The 55,764-square-foot Anderson House, which is perhaps better described as a castle, was built in 1902-1905, as the home of Larz Anderson and his wife. Upon Anderson's death, the house was given as a gift to the Society of the Cincinnati which was something of an American noble order dedicated to preserving the legacy of the American Revolution founded in 1783 after the Revolutionary War. The house serves as the organization's headquarters, and houses a museum and library with information relating to the Revolutionary War.
