The Peter Tufts House is a Colonial American house located in Medford, Massachusetts. It is thought to have been built between 1677 and 1678. Past historians considered it to be the oldest brick house in the United States, although that distinction belongs to Bacon's Castle, the 1665 plantation home of Virginian Arthur Allen. It is also believed to be, possibly, the oldest surviving house in the U.S. with a gambrel roof.
