Leiden Observatory, Leiden

Leiden Observatory (Sterrewacht Leiden) is an astronomical observatory where many notorious astronomers and physicists have been doing research. Some of them are Willem de Sitter, Ejnar Hertzsprung and Jan Oort. Of course your children won't remember this information, but the things they will see there are memories for life. The building is open to explore, search, go up and watch the stars or other phenomena. Kids adore all the things inside - different telescopes, special sun glasses and other electronic machinery that are very attractive for the little ones.
