In 1778, residents of the area around what is now Prospect Green withdrew from the Congregational church in Cheshire and formed their own ecclesiastical society, known as the Columbia Society. Their meeting house was located on the Prospect Green, which is the highest inhabited elevation in New Haven County. The Prospect Congregational Society was formally established in 1798 and continued meeting in the original simple structure until a new edifice was erected in 1841, to the west of the Green. The previous meeting house was moved to a another site nearby where it was used by the Methodist church until 1858. After a fire destroyed the 1841 building, a new fieldstone church was erected. This too was destroyed by fire and was replaced by the current church, built in 1941.
