It is one of coastal Maine's finest Greek Revival churches, and was listed on the National Register of Historic Places in 1973.

[1] The First Baptist Church is set facing east on the south side of High Street in Sedgwick, between Maine Routes 172 and 175.

Its facade is dominated by a massive projecting Greek pedimented gable temple front, supported by fluted Doric columns.

The church has a multi-stage tower that is square in the first two stages, followed by an octagonal belfry with four round-arch louvered openings, topped by a round cupola and spire.

[2] Its stained glass windows, gifts of parishioners, were installed between 1892 and 1905, and have been given unproven attributions to several noted stained-glass artists of the period, including John LaFarge and Louis Comfort Tiffany.
