Since 1684, members of the Religious Society of Friends, also known as Quakers, have met in what is now one of the country’s oldest frame houses of worship. Many well-known individuals, including William Penn and Lord Baltimore, worshipped here. The meeting grounds also include a brick Greek Revival-style meeting house dating to 1880, as well as old-growth trees and a historic cemetery. Visitors are welcome, and group tours are available on request.
