The main town square was built as early as 1366 along with the third belt of city fortifications. It has been classified as a national monument and entered on the UNESCO World Heritage List. Around the square there are Brukenthal Palace, 12th-century Town Council Tower, Haller House and a church from the first half of the 18th century
In the square you can see a statue of Gheorghe Lazăr, a scholar and thinker, considered the founder of Romanian education. There is also a commemorative granite plaque dedicated to the memory of the victims of the 1989 revolution.
Since the Middle Ages, the square has not only hosted fairs here, but also the most important city events, public meetings and executions. One of the most famous was the Saxon execution of Count Johann Sachs von Harteneck, beheaded in this square in 1703. The gallows standing on the square was not removed until 1783. In the first half of the 18th century, a special cage was also erected here, in which people disturbing peace were placed.
