The neighborhoods of Flatbush extend south from the old Brooklyn City Line north of the southern edges of Prospect Park, the Brooklyn Botanic Garden and Empire Boulevard. The southern border of Flatbush neighborhoods is approximately on the line of the Bay Ridge Branch, which runs to the south of Avenue H, the campus of Brooklyn College, and "The Junction" where Flatbush and Nostrand Avenues intersect. Flatbush's eastern border is roughly around New York Avenue, while its western border is Coney Island Avenue.
