Azadi Square , literally the Freedom or Liberty Square, is a city square in Tehran, Iran.
It has an area of about 50,000 m2, plus adjacent areas, and is the largest square in Tehran and the second largest in Iran, being smaller than Azerbaijan Square in Tabriz.
The 50 m Azadi Tower is in the centre of the square.
Before the Iranian Revolution, it was called the "Shahyad Square" meaning "King Memorial Square", and was the site of many of the Revolution's demonstrations leading up to 12 December 1979. The square was again the site of mass opposition during the 2009–2010 Iranian election protests.
