The third meetinghouse is located near the second (BU12) and was constructed in response to the second's separate and unequal women's wing. It is a superb double meetinghouse of local stone with arched window heads. It now serves the community as the William Penn Center and is used for children's daycare. This has resulted in significant changes within that make the interior of little architectural interest. The stone stable with its asymmetrical wooden roof to shelter horses in winter is a handsome, multistage example of a typical counterpart to the meeting.
