For a long time, astronomy has attracted the attention of scientists in the world and has a special place in the history of science of Iran and Islam. While the sky is half of nature, it is a forgotten nature. Under the pretext of restoring the pleasure of watching the starry sky for the audience, a doorway has been established for the public to enter the wonderful world of science. Engarium (with the local meaning of the place where imaginations are formed) is the name of this doorway. Every year, thousands of people visit this center to learn about the latest achievements of basic sciences and engineering.
