Prospect Heights has Flatbush Avenue to the west, Atlantic Avenue to the north, Eastern Parkway to the south, and Washington Avenue to the east.  In the northern section of Prospect Heights are the Vanderbilt Railyards, which could become part of the massive and controversial Atlantic Yards project.
Compared to other Brooklyn neighborhoods, Prospect Heights is relatively small and is notable for its cultural diversity as well as its tree-lined streets. Prospect Heights has seen rapid demographic changes over the last decade, and its shifts are exemplified by a mixture of older buildings under construction, rows of classic 1890s brownstones and newly built luxury condominiums.
Along the southern boundary, Eastern Parkway, from Grand Army Plaza to Washington Avenue is reminiscent of Manhattan’s fifth Avenue “Museum Mile”. Immense, opulent buildings line the north side of the parkway, and the south side features the Brooklyn Public library, Mount Prospect Park (not to be confused with Prospect Park), the Brooklyn Botanic Garden and the recently renovated Brooklyn Museum. To its north lies Fort Greene, to the south, Prospect Park, to its west, Park Slope and to its east, Crown Heights.
The interior portion of the neighborhood consists mostly of brownstone-style residential rowhouse buildings, some built as early as 1890, although some blocks, such as Lincoln and St, Johns Place between Underhill and Washington Avenues, include larger multi-unit apartment buildings. A number of new condominium complexes are under construction in many parts of the neighborhood.
