Dupont Circle Historic District: Dupont Circle's rich history is reflected by its diverse and elegant architecture.

The Dupont Circle Historic District encompasses one of the city's most elegant historic residential neighborhoods, notable for superior examples of Victorian rowhouse architecture in Queen Anne and Richardsonian Romanesque styles, as well as some of the city's finest turn-of-the-century mansions in Beaux Arts, Chateauesque, Renaissance, and Georgian Revival styles.

It has served as the home of many prominent and affluent Washingtonians, as well as foreign legations. Many prominent local and national architects are represented in this unusually rich and varied streetscape. Dupont Circle serves as the centerpiece of many of the diagonal L'Enfant avenues. The district also includes fine examples of early apartments, 1920s commercial buildings along Connecticut Avenue, modest working-class dwellings, stables, and carriage houses. Approximately 3,100 buildings dating from about 1875 to 1931 make up the district.
