Targu Mures is both industrial and sophisticated; its downtown area successfully retains its Old World charm, yet has the most contemporary feel of any Romanian city. Among the attractions are the18th-century Bolyai Memorial House, a 14th-century citadel, the 18th-century Tholdalagi House and the Palace of Culture. At the palace, see the "Hall of Mirrors," historical exhibits, a 4,700-pipe organ and wonderful stained and painted glass.
