main display was occupied by a copy of the Cyrus Cylinder, the original being kept at the British Museum. A translation of the cylinder's cuneiform inscription is inscribed in golden letters on the wall of one of the galleries leading to the museum's audio-visual center. A similar plaque facing the cylinder listed the Twelve Points of the White Revolution. Next, to the Cyrus Cylinder, there was a gold plaque commemorating the original presentation of the museum to Mohammad Reza Pahlavi by the Mayor of Tehran. Potteries, ceramics, varnished porcelains (such as a seventh-century blue and gold dish from Gorgan), an illuminated Quran, and miniatures highlighted milestones in the country's history up to the 19th century, which were represented by two painted panels from Empress and the structure was to represent Farah Pahlavi as in is stated in some ancient texts. Events Audiovisual theatre (1971) The original show, devised in 1971, was replaced in 1975 by a new one which invited visitors to discover Iran's geographic and natural diversity along with its fundamental historical elements. It exhibited a number of national achievements, technical undertakings, calligraphed poems, and miniature paintings. The project, devised by a Czechoslovak company, required 12,000 metres of film, 20,000 color slides, 20 movie projectors, and 120 slide projectors. The audiovisual programmes were directed by professor Jaroslav Frič (1928–2000). Five computers operated the entire system. Gate of Words light show (2015) German artist Philipp Geist organized a projection mapping installation named Gate of Words at the Azadi Tower, on the occasion of the German Unity Day. The show was held from October 3 to 5, 2015. In this project, the artist visualized the topics of freedom, peace, space and time in a poetical manner. Geist developed a light installation made of colored words and concepts in different languages, and abstract painterly compositions of images. The glowing words were in English, German and Persian, moving in sync with live music on the walls of the tower.
