===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 [[Czechoslovakia|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.<ref name="Khashayar"/>
