Welwyn Preserve County Park is a 204-acre (0.83 km2) public nature reserve in Glen Cove, on the North Shore of Long Island in New York State.

Welwyn Preserve was originally Welwyn Estate, the estate of the industrialist Harold I. Pratt. The main house, Welwyn, was one of the Gold Coast Mansions.

The Welwyn estate also includes woodland and other natural habitats, as well as part of the coast facing north onto Long Island Sound. The mansion is currently used as the Holocaust Memorial and Tolerance Center of Nassau County.

Welwyn was originally the estate of Harold Irving Pratt, an American oil industrialist and philanthropist who was born in 1877, and died at Glen Cove in 1939. Harold Pratt, the owner of Welwyn, was one of the sons of Charles Pratt, who was also an oil industrialist and was the founder of the Pratt Institute in Brooklyn, New York.[1]

Welwyn includes the estate's original Georgian-style mansion, which was built in 1913, and which was designed by Delano & Aldrich.

As a preserve[edit]

Welwyn Preserve is owned by Nassau County, New York, and is operated as a public preserve.[1][2] The preserve includes a butterfly garden, extensive mature woodland, salt marsh and a tidal inlet. Dogs are not allowed in the preserve, in order to safeguard the wildlife.
