The Valentine-Varian House is the home of the Museum of Bronx History. Two rooms contain changing exhibitions, while the front parlor has a permanent display about the development of the area, from the Indian and Dutch periods through the Revolution. Plantings, an herb garden, an outdoor seating area and the Bronx River Soldier monument occupy the gardens surrounding the house.
The four level fieldstone home was built by Isaac Valentine in 1758, and is the second oldest house standing in the Bronx after the Van Cortland house.
