On January 19, 1835, Reverent Steven Barnes led sixteen men and women in establishing the Weymouth Congregational Church at the home of Lathrop Seymour. From its beginnings, the congregation opposed slavery. In 1848, it adopted resolutions condemning the "peculiar institution" and asserting that Black people are "our brother[s] 'made of one blood' with us." In 1835, the church hosted public meetings featuring the abolitionist William Lloyd Garrison. A notable example of Greek Revival architecture, the meetinghouse was built in 1835-'36 and became the oldest extant church building in Medina County. The porch with Doric columns was added in 1854. The Historic American Building Survey documented the building in 1936. As the Congregational denomination struggled, the sanctuary became the home of the non-denominational Weymouth Community Church in 1920 and remained so until 2018.
