The Oak Grove Chapel, also known historically as the River Meetinghouse and the Sophia D. Bailey Chapel, is a non-denominational chapel at United States Route 201 and Oak Grove Road in Vassalboro, Maine. Built in 1786 as a Quaker meetinghouse, it was Vassalboro's first religious building. In 1895 it was restyled in the Shingle style, with a portico and tower added, and converted to non-denomination use by the Oak Grove-Coburn School (since closed). The building was listed on the National Register of Historic Places in 1977. Read more on Wikipedia
