At the edge of De Dordtse Biesbosch, you will find Sterrenwacht Mercurius Observatory. Worth a visit at night as well as during the day.
See exhibits on astronomy, meteorology and space exploration. Up in the Dome with the 1922 Carls Zeiss telescope, look at our "own" star, the sun, during the day.
At night on a clear day, gaze at that fantastic starry sky...and enjoy, for nature reaches beyond the tops of the trees.
For schools and groups, all planets of our solar system are examined in a short presentation. Of course, the observatory staff will answer your questions. After the presentation you go to the dome, where you can study the sky with the Carl Zeiss telescope from 1922 on a clear day.
