An observatory is a place for making observations. Usually it means a building that holds one or many big telescopes. Observatories are used by astronomers to look at the sky. Modern observatories are usually high up on mountains or hills, because they need clear and clean air to be able to see properly. The higher you go, the clearer, dryer and cleaner the air gets. Observatories also have to be away from places that have lots of light pollution, like cities. Too much light can make it so that the astronomers cannot see out of the telescope very well.
