The church is a modest rectangular wood-frame structure, now facing south, with a gable roof and a small tower.

The square tower has a short first stage, topped by a belfry with louvered openings and pilasters.

The building has seen numerous alterations, and most of its decorative elements are the result of Greek Revival renovations in 1840.

[2] The cemetery is about 1 acre (0.40 ha) in size, and is bounded on three sides by a low stone wall, believed to date to 1733, and on the fourth by the Piscataqua River.

An iron gate, mounted on concrete posts with round-arch panels and finials, was added to the north entrance in 1910.
