China Science and Technology Museum was opened to the public in September 1988. But the second project was completed in May 2000. Its main task is to spread knowledge of science and technology among the public.
The activities of China Science and Technology Museum include popular science exhibitions, Astro-vision film shows, training education programs and experiment exhibition programs. The museum has an area of 40,000 square metres, of which 16,000 square metres is for exhibition halls.
The Astro-vision Theatre is one of the museum’s major attractions and also one of the largest Astro-vision theatres in the world.
