Northampton Unitarian Church is from 1904. The congregation was formed in 1825 and built a Greek Revival church at this site. Fire struck in 1903 and this present structure was built. As a temporary location in 1904 they were at the high school assembly hall. The congregation called their church the Second Congregational Church and had unitarian beliefs. The Free Congregational Society of Florence was also Unitarian and joined with the Northampton Unitarian Church at some point.
