Trowbridge Square Historic District

The noted abolitionist Simeon Jocelyn (1799-1879) developed Trowbridge Square in the 1830s in partnership with architect and builder Isaac Thompson. The area was established for New Haven’s low-income working-class population and was meant to be a model egalitarian residential community populated by African Americans and whites. Restrictive covenants on the sale of alcohol and racial discrimination sought to improve the residents’ quality of life. A school for African Americans was built on Carlisle Street to further encourage them to move to the area, and, by 1845, African Americans made up almost 58 percent of the Trowbridge Square population. The district is on the National Register of Historic Places.
