The astronomy tower of the Sorbonne is open to visitors. Come and discover the old observatory of the university's students. The dome of the Sorbonne Observatory, which houses a telescope built in 1935, dominates Paris from the top of its 40 meters and allows a clear field of observation of almost 360°. Underneath, an optical workshop houses mirrors that are polished.
The visit takes place in several stages. First, the lecturer recounts the history of the Sorbonne and then the ascent to the stars begins.
The visits are led by passionate and fascinating guides between explanation and demonstration. If the sky is clear you can observe the moon and the stars through a telescope dating from 1935. On the other hand, if the sky is cloudy, you will be able to observe the extraordinary view of the whole of Paris.
It is by small groups of 5 that you will be able to visit this exceptional place, whose access is however reserved to the people not having fear of climbing stairs. Indeed, an elevator leads to half height and the rest of the tour is done on foot.
This is an exceptional opportunity to enter this place, which is open 2 to 3 nights a week.
It is an unusual visit for all lovers of history and history of science.
You can access the tower by crossing the main courtyard, where you can see a sundial and the old chapel built by Richelieu where he is buried.
The visit is by reservation only.
