In 1932, Robert Moses had a replica of Mount Vernon built in Prospect Park to mark the 200th anniversary of George Washington’s birth. The building was constructed by Sears, Roebuck & Company (who also delivered another replica to the Exposition Coloniale Internationale in Paris in 1931, which still stands as a private home) and designed by architect Charles K. Bryant.
The structure only stood for a mere two years before being torn down. It was one of the shortest lived buildings in New York City. The house was located at the base of Lookout Hill on the Peninsula of the Lake.
