Built in 1804, its interior was extensively restyled in the second half of the 19th century to resemble a Gothic English country church.

[1] St. John's is located in the center of the Warehouse Point village, just south of the junction of Main and Bridge Streets.

It is a tall single-story wood-frame structure, with a projecting entry section, and a two-stage square tower housing a clock and bell.

As originally built, it had a fairly traditional 18th-century meetinghouse plan, with a flat ceiling, galleries on the sides, and a Palladian window behind the pulpit.

In 1855, the congregation retained the New Haven firm of Henry Austin to redesign it in the Gothic style.
