In recent decades, the preservation of historic buildings, neighborhoods, and landscapes has become a significant basis for regulation of private property, as well as an important motive for public and charitable ownership. In the District of Columbia, for example, there are over 25,000 buildings and 43 historic districts protected. This seminar examines the theory and practice of historic preservation. The practical focus of the course will be on the nationally significant law and institutions in the District of Columbia and how they might be improved. Students will have opportunities to hear from recognized preservation experts and architects, visit several districts, attend public proceedings of the DC Historic Preservation Board, and meet with actual participants in controversial preservation battles. Each student must complete a substantial original research paper, as the seminar satisfies the upperclass writing requirement.
