On the final day, the Shah inaugurated the Shahyad Tower (later renamed the Azadi Tower after the Iranian Revolution) in Tehran to commemorate the event. The tower was also home to the Museum of Persian History. In it was displayed the Cyrus Cylinder, which the Shah promoted as "the first human rights charter in history".[11][12] The cylinder was also the official symbol of the celebrations, and the Shah's first speech at Cyrus' tomb praised the freedom that it had proclaimed, two and a half millennia previously.
