The tower consists of four bases which inside two elevators in two bases and two staircases in two further crossed bases.
The square is almost oval. The large diameter is 380 meters in length along the axis of the East - West and small diameter is 210 meters along the North – South
Built in 1971 in commemoration of the 2,500th anniversary of the Persian Empire, this "gateway into Tehran" was named the "Shahyad" (King's Memorial) in honor of the Shah, but was changed to "Azadi" (Freedom) after the Revolution of 1979. It is 50 meters (164 ft) tall and completely clad in cut marble
In the second half of the fourteenth century A.H.S, the design of western gateway of Tehran, adjacent to the Mehrabad International Airport and many of the paths leading to Tehran are launched with the aim of memorial building in addition to specific visual effects, associate history, arts and culture of this country and consider it as a symbol of the Iranian capital
The structures of the tower that starts from the top of the bases and covers around the top rack of the dome, are inspired by the Seljuks and the Ghaznavids (seventh century AD) and also for example, Aladdin tower in Varamin can be mentioned
The entrance to the tower is directly underneath the main vault and leads into the Azadi Museum on the basement floor. The black walls and proportions of the building are austere. Heavy doors open onto a crypt with subdued lighting issuing from showcases, each containing an object. Gold and enamel pieces, painted pottery, marble, miniature, and paintings are located among black marble walls. A concrete mesh forms the ceiling. Approximately fifty pieces have been selected, each representing a particular period in Iran's history.
The main display is occupied by a copy of the Cyrus Cylinder (the original is in the British Museum). A translation of the cuneiform inscription on the cylinder is inscribed in golden letters on the wall of one of the galleries leading to the museum's audio-visual department; opposite, a similar plaque lists the Twelve Points of the White Revolution. Next to the Cyrus Cylinder, a gold plaque commemorates the original presentation of the museum to the Mohammad Reza Pahlavi by the Mayor of Tehran.
Among the earliest items on display are square flagstones, gold sheeting, and terra cotta tablets from Susa, covered with uniform cuneiform characters. Potteries, ceramics, varnished porcelains (such as a seventh-century blue and gold dish from Gorgan), an illuminated Koran, and miniatures highlight milestones in the country's history up to the nineteenth century, which is represented by two painted panels from Empress Farah Pahlavi's collection.
Built with white marble stone from the Isfahan Province, it includes eight thousand blocks of stone. The stones were all located and supplied by Ghanbar Rahimi, whose knowledge of the quarries was second to none and who was known as "Soltan e Sang e Iran" (Iran's Sultan of Stone). The shape of each block was calculated by computer, and programmed to include all the instructions for the building's work. The actual construction of the tower was carried out, and supervised by Iran's finest master stonemason, Ghaffar Davarpanah Varnosfaderani. The main financing was provided by a group of five hundred Iranian industrialists. The inauguration took place on October 16, 1971.
The iconic Monument des Martyrs in Algiers (built, 1982) shows a strong influence by this monument, in its general design as well as its details.
