The Wyckoff House | Built around 1652, the original portion of this house is thought to be the oldest surviving structure in New York City. The Wyckoff House (or "that place by the McDonald's", as someone in the neighborhood later described it to me) was the first landmark designated by the city's Landmarks Preservation Commission, and it now serves as a museum; you can get a good look around the place by watching the video at the bottom of this page.
Oh, and speaking of Wyckoffs...
