Built in 1772 and moved to its present site in 1775, it is one of the town's original three meeting houses.

[1] When Bristol was settled the land area was larger than today and the distance required to travel to the meeting house was such that three meeting houses were built to serve the Presbyterian population, the others being at Broad Cove (destroyed) and the Walpole Meetinghouse.

The framing for the Harrington meeting house was originally erected in the village of Bristol Mills in 1772 but was "pulled down" and re-erected at the head of John's Bay in 1773.

[4] The interior was made into a "back to" or "reverse plan" arrangement which means the entry doors are behind the pulpit.

This type of king post truss is rare but other examples have been noted in such as in the 1714 Lynnfield, Massachusetts meeting house, 1800 Congregational Church in Windham, Vermont, and the 1799 Strafford, Vermont meeting house.
