The Fourth Ecclesiastical Society of Windsor, or North Society, was established in 1752 and a meetinghouse was soon built near the Scantic River. In the late 1790s, there were intense debates over the issue of enlarging the building. A decision was finally reached to expand the meetinghouse, but it burned down on April 20, 1802. There was then a violent contoversy and accusations of arson, but a new meetinghouse on the same site was soon completed. In 1768, East Windsor had separated from the town of Windsor and in 1845 South Windsor separated fom East Windsor. The Congregational church in the East Windsor Hill section of the new town of South Windsor had been the First Church of East Windsor, but then became the First Church of South Windsor, while the former North Society Church in the Scantic section of East Windsor became the First Church of East Windsor. The church‘s exterior walls were extended in 1842. That same year, interior floor space was also enlarged, when the the empty space between the balconies above the main floor was floored over, creating a new upper floor for religious services. The lower floor was later known as Library Hall, because the town’s public library was located there from 1907 to 1920.
