Oldest building in Yonkers. The old manor house of the Philipse family which OWNED all of Yonkers (and most of Westchester County and the Bronx). It was built next to the Saw Mill River (which is now underground). It is now a National Historic Site operated by the state of New York. It was for many years the town hall of Yonkers. The interior is extremely bland because the structural integrity of the builiding is a bit inept.
