Decode Prospect Park.

What Olmsted Buried in Brooklyn

Frederick Law Olmsted and Calvert Vaux considered Prospect Park their finest work — better even than Central Park, which they had completed just a few years earlier. They were given 585 acres of Brooklyn farmland in 1866 and proceeded to bury it. Literally. The park's rolling meadows, its lake, and even the Fallkill Creek that feeds the Lullwater were all constructed from scratch, the original terrain reshaped with millions of cubic yards of fill. The only genuinely natural water in the entire park is a small spring near Lookout Hill — everything else is an illusion of nature, engineered to feel wilder than the city that surrounds it.

Before Olmsted arrived, this land held the most significant engagement of the American Revolution in New York. On August 27, 1776, the Battle of Long Island was fought across what is now the park's eastern edge and the neighborhoods beyond. Washington's Continental Army held the high ground at Lookout Hill — at 197 feet, the highest point in Brooklyn — while British and Hessian troops encircled them. The retreat that followed, a midnight crossing of the East River to Manhattan, saved the entire army. A granite monument near the Maryland Monument entrance at Ninth Street commemorates the 400 Maryland soldiers who died covering Washington's escape. Most park visitors walk past it without reading a word.

Deeper inside the park, the Vale of Cashmere sits almost entirely unknown — a formal garden built in 1894 near the northeast corner, now overgrown and haunting, its granite fountain crumbling and its walls covered in moss. The Concert Grove, with its busts of classical composers arranged in a semicircle at the edge of the lake, was added in the 1870s and fell into disrepair for decades before partial restoration. A StoryHunt through Prospect Park traces these layers: the engineered landscape beneath the natural one, the battlefield beneath the picnic grounds, and the forgotten corners that even lifelong Brooklynites have never found. Your phone guides you to the spring, the monument, and the garden — no map, just clues.
