Joneboro Union Church was originally built in 1840 but underwent major renovations in 1911. Jonesboro is a small Maine community, but had three churches when this one was established. By the 20th century, the Baptist and Universalist churches were no longer active leaving the Union Church as Jonesboro’s last. To accommodate the larger crowd, the church was moved back 20 feet and enlarged. Because of its unique mix of Gothic Revival, Tudor and classical elements, it was added to the National Register of Historic Places.
