The Chestnut Hill Meeting House was built in 1769 in what was then the South Parish of Mendon. The meeting house, one of the best preserved in New England, shares many characteristics with the eighteenth-century meeting houses studied in Phase I of SPNEA’s dendrochronology project.
The meeting house is about forty feet wide by thirty-five feet long, and has box pews covering the first floor and galleries on three sides above. There are five structural bays. Adjustments were made in the size of the bays in order to accommodate supports for the galleries and to allow for the width of the pulpit. The roof frame consists of six king post trusses with braces between the king post and rafters and from the king posts to the tie beams. Perhaps owing to the building’s comparatively modest size, the roof frame has single, rather than double, rafters. Joists flush with the bottoms of the tie beams suggest that a plaster ceiling was anticipated. The camber of the tie beams gives the current matchboard ceiling a slight curve.
Alterations in the nineteenth century included installing plaster and lath on the walls, replacing the windows and doors, boxing posts next to the pulpit and replacing box pews in the center part of the floor with slip pews. The original pews were reinstalled by 1935.
