The Conference House, Tottenville

The Conference House, (also known as the Bentley Manor and the Captain Christopher Billop House) was built before 1680 and located near the southern most tip of New York State in Staten Island. It is famous for the Peace Conference held there on September 11, 1776, which unsuccessfully attempted to end the American Revolutionary War. The House, a National and New York City Landmark, is the only pre-Revolutionary manor house still surviving in New York City. It stands majestically in Conference House Park overlooking Raritan Bay.
