Lexington's entire downtown is listed on the State and National register of Historic Places. As the Rockbridge County seat, it has long been the center of commerce and social activity for the area. The architecture of the downtown, as well as the surrounding residential district, is fascinating and has been carefully restored. Thomas U. Walter, who designed the dome on the U.S. Capitol, also designed the Lexington Presbyterian Church and the former Rockbridge County jail, which now serves as Kappa Alpha's national headquarters. The downtown offers exceptional shopping including unique gift shops, fresh-made chocolates, fresh-roasted coffees, works by local artisans, book stores, clothing shops and a wide variety of restaurants, all within walking distance. Three inns are found in the heart of the historic district.
