3. Seguine Mansion

In 1838, Joseph Seguine constructed the Greek Revival mansion on land originally purchased by his grandfather in the 1780s. The family remained in the house through the Civil War but were forced to sell it when they ran into financial troubles. The Seguines repurchased the house in 1916 and remained there until 1981. In 1989, the mansion was sold to New York City and is now a member of the Historic House Trust of New York.
