Inspiration Point originally was just a clifftop overlooking the Hudson in Northern Manhattan, at roughly 190th Street. It was right alongside the northern extension of Riverside Drive. A Greek temple was built at Inspiration Point in 1925. The temple was upstairs at the clifftop. Below were restrooms.
Inspiration Point is mentioned in the last verse of the song I’ll Take Manhattan. Miss Ella Fitzgerald:
The northern extension of Riverside Drive was replaced by the Henry Hudson Parkway in 1937, cutting off Inspiration Point from almost all visitors.
The Hudson River Greenway, a riverfront park with a bike lane running from Battery Park to Dyckman Street, opened fully in 2010. Once again, people are able to stop at Inspiration Point, but only on foot or by bike. No train, car or bus comes here.
Hope you enjoy my singing!
