The Endale Arch opened to the public in the 1860s. One of the first architectural elements constructed in Prospect Park, the arch was envisioned by park creators Frederick Law Olmsted and Calvert Vaux as a transporting entrance from the urban hubbub of Grand Army Plaza to the pastoral tranquility of the mile-long Long Meadow. For our purposes, the arch’s natural acoustics creates a mesmerizing resonance. In our acoustic experiments at the arch, we found that at either end of the arch we could play music, but hear each other as if we were standing inches apart.
