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 (other sources say Ave, H-Ave T./Ralph Ave.-Nostrand Avenue. – again, N/S/EW).
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 Reformed Church.
