Welwyn Preserve, Natural preserve in Glen Cove, New York, US.
The 204-acre preserve features walking trails, woodland areas, salt marshes, and butterfly gardens across the North Shore of Long Island.
Harold Irving Pratt, an oil industrialist, built the Georgian mansion in 1906, which remained a private estate until Harriet Pratt's death in 1969.
The Holocaust Memorial and Tolerance Center now operates in the main house, offering educational programs and exhibits about this historical period.
The preserve welcomes visitors Monday through Friday from 10:00 AM to 4:30 PM and weekends from noon to 4:00 PM, with no dogs permitted.
The property contains abandoned greenhouses with cement basements that once served as a training facility for the Nassau County Sheriff's Department.
