An official Path Through History Site! Built by English immigrant Captain Christopher Billopp around 1680, this stately manor was a wheat farm throughout the first century of its existence. The Conference House was the site of a 1776 peace conference which attempted to end the Revolutionary War. Edward Rutledge, John Adams, Lord Howe and Benjamin Franklin were among those in attendance. Surrounded by lush acreage of forests, marshland and meadows, the Conference House overlooks the Arthur Kill River, Lower Raritan Bay and New Jersey.
