The Azadi Tower (Persian: برج آزادی‎,; translated: Freedom Tower), previously known as the Shahyād Tower, is the symbol of Tehran, the capital of Iran, and marks the west entrance to the city.
The architect, Hossein Amanat, won a competition to design the monument, which combines elements of Sassanid and Islamic architecture. Amanat, was driven from the country by the revolution against the Shah of Iran and the removal of religious pluralism. It is part of the Azadi cultural complex, located in Tehran's Azadi Square in an area of some 50,000 m².
