Morningside Heights is bounded by the Upper West Side to the south, Morningside Park to the east, Harlem to the north, and Riverside Park to the west. The streets that form its boundaries are 110th Street on the south, Riverside Drive on the west, 125th Street on the north, and Morningside Drive to the east. The main thoroughfare is Broadway. With the recent gentrification of Bloomingdale, the neighborhood immediately to the south of Morningside Heights, the southern boundary of this region is sometimes stretched to 106th Street and at times even 96th Street.
Many apartment buildings and rowhouses, amongst the first to use elevators in residential buildings, were built for New York's prosperous middle class in the first two decades of the twentieth century and most of these buildings are still extant.
