Silesian Planetarium in Chorzow (Königshütte)

A planetarium is a building which has a dome-shaped ceiling with a special projector in the middle. It is used to present educational shows on astronomy, and sometimes celestial navigation.

The building itself often (but not always) has a domed roof. Styles of planetariums vary; additional rooms are often included, and sometimes a flat or slanted roof covers a dome-shaped mesh or screen. The projector in the center of the planetarium's main room projects a simulation of a night sky, which can be adjusted to any time of the night and year.^[1]
