About Flatbush

View All Flatbush Listings

Flatbush features one of Brooklyn's most varied housing stocks, including grand detached Victorians along Ocean Avenue, limestone and brownstone rowhouses, prewar apartment buildings, and brick townhomes within landmarked enclaves like Prospect Park South and Ditmas Park. The Q, 2, and 5 trains connect the neighborhood to Manhattan, while Prospect Park's 526 acres of green space border the northern edge. The restored Kings Theatre, a 1920s-era landmark performance venue, and Erasmus Hall High School, founded in 1786, are among the area's most notable architectural features.
