Reid Chapel (named for the Reid family who worshiped at First & Franklin) was originally a multi-purpose space that was re-designated a chapel in 1940 with an interior renovation. The space continues to be used as a chapel, art gallery, and meeting space for organizations in the Mt. Vernon neighborhood.
