Washington, D.C., is well known for its European heritage, going all the way back to Pierre Charles L’Enfant’s development of the 1791 plan of the city, which was modeled after Paris: the plan superimposed a grid along with integrated avenues, plazas, and designated sites for major federal buildings. Yet the construction and in some cases the design of scores of Washington’s landmarks was accomplished not only by European but also by African American builders and architects.
