It was built in 1754-55 and restyled in 1839 for a congregation whose history dates to the founding of the community in the 17th century.
Its main facade is three bays wide, surmounted by a tower with clock, bell, and steeple.
A full entablature extends across the front and sides of the building, and there is a triangular ornament at the center of the tympanum.
The church congregation, originally Congregationalist in outlook, was subject to schism between Unitarian and Trinitarian factions, with the latter group departing 1826.
The greenspace in front of the church was where the local militia company gathered in April 1775 to join the Battles of Lexington and Concord.
