Flatlands is a neighborhood in the New York City borough of Brooklyn. The area is part of Brooklyn Community Board 18. The neighborhood borders are roughly delineated by Flatlands Avenue on the North, Avenue U to the south, Ralph Avenue to the east, and Flatbush Avenue to the west. Flatlands is one of the few Brooklyn neighborhoods not served by many subway lines; those that do serve it are the IRT Nostrand Avenue Line (2 5) at the Junction of Flatbush and Nostrand Avenues, and the BMT Brighton Line (B Q) (connected by city buses on Avenue L and Kings Highway). City bus lines serve the neighborhood. There are several historical structures in Flatlands, including the Hendrick I. Lott House (East 36th Street between Fillmore Ave and Ave. S, built around 1720), which was a stop on the Underground Railroad, and the Flatlands Dutch Reformed Church.
