Every noon, the Sun winks at the meridian.
From 1783 to 1940, the Philippe le Bon Tower was an astronomical observatory. One of the 11 most important in Europe, equipped with the most beautiful instruments. It is even suspected that the Tower was built for astronomical observations in the time of Philip the Good, when the Burgundian Court was one of the most radiant in Europe.
The visit, which is twice as long as a traditional ascent of the Tower, takes place in two stages. First of all, you will see a ray of sunlight land on the 18th century meridian, which is still visible, at around 12:40. Why 12:40? Why around 12:40 and not at 12:40?
Then, the guide of the Astronomical Society of Burgundy tells you about the observatory, a story with many twists and turns, from the Middle Ages to the Occupation, through the Enlightenment, between sciences and fascinating characters. Projections, experiments, observations, while waiting to reinstall the real instruments that were used there.
Note: the visit is not recommended for pregnant women or people with difficulty in moving around (316 steps).
"As part of the Vigipirate plan and for security reasons, no personal effects may be kept at the reception or at the foot of the Philippe Le Bon Tower (luggage, pushchairs, etc.).
We invite you to make your arrangements before the start of the visit.
