Coindre Hall is a Medieval French Chateau style mansion that was built between 1906-1911 for George McKesson Brown. Mr. Brown lost his fortune and this mansion in the stock market crash of 1929. Subsequently, it became a school run by the Brothers of the Sacred Heart (1939-1971) and was briefly known as the Eagle Hill School in the 1970’s. It is listed on the National Register of Historic Places and is a Suffolk County Park.
