Morningside Park was considered by Samuel Parsons, Superintendent of Parks at the time of its completion, as "perhaps the most consummate piece of art that [Calvert Vaux] ever created." That's certainly high praise for a work by this partner in perhaps the most revered landscape design team in US history - Olmsted and Vaux, who together designed New York City's Central Park, Prospect Park, portions of Riverside Park and many parks in other American cities. Morningside Park was completed in 1895, the year Calvert Vaux died, which makes this park the final collaboration that both partners lived to see to completion. The park also remains arguably the most intact of all of their designs. Using early photographs from the Urban Archive our story explores the design challenge Olmsted and Vaux encountered, the changed urban landscape they had to contend with over the long years of planning and execution (1873-1895) and the brilliant execution of their final design.
