The old Newtown Presbyterian church is remarkable for its squared brownstone ashlar masonry and for its square-headed oversized windows along the sides. A large polygonal apse, added later at the west end, marks the change from the reverse orientation that differentiates the Presbyterians from the usual Anglican model. The presence of this monumental church with its beautiful stonework attests to the growing wealth of the community despite the loss of the county seat in 1813. The large oval marble plaque on the front lists building dates of 1769 and repairs in 1842. The congregation was founded in 1734; a small stone building at the rear, later used for a school, may have been the original church. A similar building was constructed for the Southampton Baptist Church (c. 1772) at 1101 S. 2nd Street Pike (PA 232) in Southampton.
