[1] At that time, under the theocratic structure of the New Haven Colony, the town of Guilford and its church were essentially the same entity.
[1] Guilford's first meeting house was a simple stone structure with a thatched roof, located on the town green.
It was expanded in the 1660s, 1670s, and 1680s, and finally replaced in 1713 with the construction of a larger building, also on the green, that is reputed to have been the first church in Connecticut with a steeple clock and a bell.
[1][3] The current church building, a wooden structure that overlooks the town green, was completed in 1830 as part of a campaign to clear the green of buildings.
All six churches have front porticos with four fluted columns, the doors of all six have the same dimensions, all six steeples are of the same design and are surmounted by weathervanes that appear to have been cast from one mold, and all six churches have twenty-over-twenty double-hung windows.
