This guided walking tour will highlight the architecture and history of this historic neighborhood. Named after the first federal architect who designed the circa- 1823 Robert Mills House and the circa- 1828 Asylum, today’s Robert Mills District was listed in 1971 within the National Register of Historic Places as “Columbia Historic District II.” Bound to the west by Sumter, the north by Calhoun, the east by Barnwell, and the south by Taylor, this district contains approximately 113 historic structures embodying more than three centuries of diverse residential and institutional architecture.
