The Manor (Glen Cove, New York)

The Manor is a historic mansion in Glen Cove, New York. It was constructed in 1910 as the home of John Teele Pratt and Ruth Baker Pratt. It was designed by Charles A. Platt.

In the 1950s, it was used as a location for the films North by Northwest and Sabrina. After the death of Ruth Pratt in 1965, it became one of the first conference center hotels in the United States in 1967. It was known as Harrison House until 1985, when it was renamed the Glen Cove Mansion Hotel and Conference Center.

The Manor is one of five existing mansions in Glen Cove built for the sons of oil magnate Charles Pratt. The others are "The Braes", now the Webb Institute of Naval Architecture; "Welwyn", now the Holocaust Memorial and Tolerance Center of Nassau County on the grounds of the Welwyn Preserve; "Poplar Hill", now the Glengariff Healthcare Center, and "Killenworth", now the country retreat of the Russian delegation to the United Nations.
