Mt. Prospect Tower and The Old Reservoir

Tower that was located in the area of the Mt Prospect playground.

A view of Grand Army Plaza. Perhaps taken from the tower.

Nice glass plate photo of Grand Army Plaza area under construction.

A Photograph taken of the view from inside the tower.

The Brooklyn Museum going in before Eastern Parkway is finished.

A view of the old reservoir that was sited just behind the Post Office in what is today an area of Brooklyn Botanical Gardens.

Not sure if this was the view of the pump house along Flatbush Ave or not.

I found most of these old photos at the Brooklyn Museum of Art web site.

Mount Prospect is named for its sweeping views (some no longer possible) of Manhattan, Brooklyn, and parts of New Jersey and Staten Island to the west, the Atlantic Ocean to the south, and Long Island to the east.^[1] Peak elevation is 200 feet (61 m) above sea level.^[2] It was a lookout point for the Continental Army in 1776. The Battle of Long Island (sometimes called Battle of Brooklyn) was fought nearby.^[1]
In 1856, the then City of Brooklyn built a reservoir atop Mt. Prospect,^[1] soon to be supplemented by the larger Ridgewood Reservoir. In 1860, Mt. Prospect was to be included in the city's ambitious new Prospect Park, to be designed by Calvert Vaux and Frederick Law Olmsted, who were in the process of designing the more famous Central Park for New York City. The designers felt that the fact that Flatbush Avenue, the main roadway from Brooklyn to Flatbush would cut through the park meant that the eastern portion of potential parkland including Mt. Prospect should not be included.^[1]
Brooklyn City kept control of the land, which then passed to the City of Greater New York in 1898. Various plans were made for the rejected parkland, including its division into city streets and lots. The major portion of the land became Institute Park, a private park, which was developed into today's Brooklyn Botanic Garden, still a private institution.
The City retained the reservoir at Mount Prospect until it was deemed obsolete due to the shifting of the New York City water supply system to sources in Upstate New York. In 1940, Mount Prospect Park was moved to the Parks Department as a city park and playground.^[1]
