Located in the heart of the Shockoe Bottom neighborhood in Richmond, the Shockoe Valley and Tobacco Row Historic District was originally listed in the Virginia Landmarks Register in 1981 and in the National Register of Historic Places in 1983. The roughly 129-acre district is an intact mixed-use neighborhood that includes residential, commercial, and industrial buildings, with historic development in the district largely following the historic street grid system laid out by Major William Mayo in 1737.  An updated period of significance justified this boundary increase that adds five new contributing buildings to the district. The 4.7-acre Shockoe Valley and Tobacco Row Historic District Boundary Increase area shares much of the same history and development patterns as the original district and incorporates additional 20th century residential, commercial, and industrial development along East Broad Street. These buildings were previously included in the City of Richmond’s local Shockoe Valley Old and Historic District but were not included within the original National Register district boundary.
