Orchard Beach, Bronx: Man‑Made, Not an Eroded Mountain

Orchard Beach in the Bronx, NYC, is a man‑made beach created in the early 1930s by Robert Moses. It was built on former marshland (Pelham Bay) using sand fill—not by erosion of a mountain.

The project transformed a tidal wetland into a 1.1‑mile crescent beach with a promenade, becoming a beloved urban seaside escape.
