Coindre Hall
 Coindre Hall is a 40 room 30000-square-foot (2800 m2) mansion in the style of a medieval French château constructed in 1912 for pharmaceutical magnate George McKesson Brown. It overlooks 34 acres (14 ha) of rolling land including a boathouse on the north shore of Long Island adjacent to Long Island Sound. Brown lost ownership of the property after the stock market crash of 1929.
