The Azadi Tower (Borj-e Azadi meaning in English: Freedom Tower) is the symbol of Tehran, the capital of Iran, and marks the entrance to the city.
Built in 1971. It is the symbol of the country's revival. It is 50 metres (148 feet) tall and is completely clad in cut marble.
The architect, Hossein Amanat, won a competition to design the monument. Azadi Tower combines Sassanid and Islamic architecture styles. In the design, such as having exactly nine stripes on each side, and exactly nine windows either of the long sides of the building. It is part of the Azadi cultural complex, located in Tehran's Azadi square in an area of some 50,000 m². There is a museum and several fountains underneath the tower.

Museum
The entrance of the tower is directly underneath the main vault and leads into the basement. The black walls, the pure, sober lines and the proportions of the whole building create an intentionally austere atmosphere. Heavy doors open onto a kind of crypt where lighting is subdued. The shock is immediate. The lighting there seems to issue from the showcases placed here and there, each containing a unique object. Gold and enamel pieces, painted pottery, marble, the warm shades of the miniatures and of the varnished paintings glitter like stars among the black marble walls and in the semi-darkness of the concrete mesh which forms the ceiling of this cave of marvels. There are about fifty pieces selected from among the finest and most precious in Iran. They are in excellent condition and each represents a particular period in the country's history.
The place of honour is occupied by a copy of " Cyrus's Cylinder" (the original is in the British Museum). The translation of this first "Declaration of Human Rights" is inscribed in golden letters on the wall of one of the galleries leading to the museum's audio-visual department;

Audio/Visual Theatre
A first show, devised in 1971, was replaced in 1975 by a new one which invited the visitor to discover Iran's geographic and natural diversity along with its fundamental historical elements. The landscapes and works of art, the faces and achievements, calligraphied poems and technical undertakings, the life and hopes of a population were shown through its ancient miniatures as well as through the smiling studiousness of Iran's new children generation.
This creative "Sound and Light" performance was devised by a Czechoslovak firm. 12,000 metres of film, 20,000 colour-slides, twenty movie projectors and one hundred and twenty slide-projectors were required. Five computers operated the entire system.
