Azadi Tower has 4 pillars, the foundations of each of which are sunk 5 meters below the ground level. Azadi Tower is resistant to an earthquake with a magnitude of 7 to 5.7 on the Richter scale.

In 1345, the call for the design of the symbolic tower of the city of Tehran with the previous name of Shahyad Aria Mehr was given. One of the eligible conditions for the design of the structure is that the plan should not be more than 45 meters (due to the proximity to Mehr Abad airport). They judge. Among the participants who present their plans, the plan of a 24-year-old young man named Mr. Hossein Amanat; A graduate of architecture from Tehran University wins the competition. The construction of Azadi Tower began three years later in 1348, and its construction was completed in two and a half years in 1350; The construction started on May 1348 and the construction ended on October 24, 1350. Operation is on October 26, 1350.

The Freedom Tower was built to remind us of the king. But 7 years after its construction, with the arrival of Imam Khomeini (RA) in Iran, it became a symbol of the freedom of the Iranian nation. Mr. Amanat said in an interview that he is very happy that this place is no longer Shahyad and that it is Azadi Square and has become a symbol of Iran's freedom.

Mr. Hossein Amanat used a combination of architecture before and after Islam (Iranian places of worship) and modern architecture in the design of Azadi Tower, which includes the following:

• Azadi Tower is designed with 4 main pillars, the 4 pillars of the tower are a symbol of the four arches of the Zoroastrian period (the four arches of Niaser Kashan) and the domes of Iranian mosques.
• The area of the square is an oval-shaped space, most of which is made up of green space. For a more beautiful design of the square and Azadi Tower, using Iranian Islamic architecture, a 6-6-sided design is designed in 3 rows of 20 Used from above in the aerial plan of Azadi Square that we are looking at, this design is similar to a honeycomb. The name of this design is honeycomb and it is inspired by the interior design of the dome of Sheikh Lotfollah Mosque in Isfahan, which is one of the best examples of Iranian Islamic architecture.
• The fountains on the level of the square are symbols of Iranian gardens such as Fin Kashan Garden, Mahan Garden in Kerman, Eram Garden in Shiraz, etc.
• The structure of Azadi Tower is designed from reinforced concrete or reinforced concrete, but it can be seen from the exterior of the stone.
• The number of stones for the facade of Azadi Tower is 25,000 pieces in 15,000 shapes, different weights and sizes, made of marble from Joshghan mines in Isfahan. The floor surface of the Azadi Tower complex is made of granite from Marwarid mines in Kurdistan, and the stone of the entrance and exit doors of Azadi complex, each of which weighs 3500 kilograms, is made of granite from Hamadan mines. As it is known, all the materials that were used inside the Azadi Tower were all from Iran's mines, and Mr. Qanbar Rahimi was responsible for the preparation of these stones.
