6. Glen Cove Mansion
The brick Georgian mansion of Glen Cove Mansion–also known as The Manor–was the 1910, 55-acre estate of John Teele, an attorney and executive for the Standard Oil Company, and Ruth Pratt, the first Republican congresswoman from New York state. Designed by Charles Platt, it was designated one of the best twelve Country Houses in America. The surrounded area comprises many former prestigious Pratt family estates, such as Kllenworth, Poplar Hill and The Braes & Wlwyn–all built on a combined 1100 acres in Glen Cove, New York.
The estate was owned by the Pratt family until Ruth’s death in 1965. In 1967, the Glen Cove Mansion Hotel became one of the first conference center hotels in the United States. Today the opulent manor features 187 guest rooms, including four suites, private dining rooms, and outdoor reception areas with a vista of the mansion’s formal gardens.
