Delaware Park was designed as part of a coordinated system of parks, parkways, and traffic circles in the city by Frederick Law Olmsted. Constructed in 1871 and covering 350 acres, Delaware Park is the centerpiece of the Buffalo, New York parks system.

Named simply The Park by Olmsted, it was later renamed in ultimate reference to the Lenape Eastern Algonquian tribe known to Europeans as the Delaware.

The Buffalo, New York public parks and parkways system is the country's oldest coordinated system of such recreational spaces, designed by Frederick Law Olmsted and Calvert Vaux between 1868 and 1896. It was inspired in large part by the parkland, boulevards, and squares of Paris, France [1]. It is currently on the National Register of Historic Places and is maintained by the Buffalo Olmsted Parks Conservancy.
