Sighișoara, town, Mureș județ (county), central Romania. Situated in the historic region of Transylvania, it is 40 miles (65 km) northeast of Sibiu city and 110 miles (175 km) northwest of Bucharest. The town circles a hill, on the summit of which stands a citadel with a ring of walls, nine extant towers (including the “Tower of the Clock”), and a number of medieval churches. Settlement of the area dates from the Bronze Age and, later, the era of Roman Dacia, but the town itself originated in the 12th century when it was colonized by Saxon Germans. In the 14th century they secured its designation as a free city, enabling it to become an important centre of trade by the second half of the 16th century. Much of the lower town had to be rebuilt after being ravaged by fire in 1676. The historic centre of the town was inscribed on UNESCO’s World Heritage List in 1999. Pop. (2007 est.) 32,570.
