La Pyramide Hall

The Pyramid of Juvisy The first stone of the obelisk known as the Juvisy pyramid was laid on 14 May 1756 in the presence of Le Monnier, d’Alembert and Trudaine de Montigny. It was a monument commemorating the measurements made by Abbé Picard in the previous century, around 1670, to measure the Villejuif-Juvisy geodetic base. Around 1970, the widening of the R.N. 7 moved the obelisk from its original location on the side of the road; its current location is therefore only of symbolic interest.

Camille Flammarion Hall

The Camille Flammarion Observatory With its 5-metre high dome, the Camille Flammarion Observatory, classified as a historical monument by the Ministry of Culture since March 2010, is a historical jewel. It is a place of heritage not only for the people of Juvis, but also for the people of Essonne and the Ile-de-France. Built in 1730 and located on the Avenue de la Cour de France (now National 7), the Camille Flammarion Observatory was originally a building that served as an inn for the Court, which regularly visited Fontainebleau.

It became national property during the Revolution in 1791, and was later sold and used as a post house. In 1814, Napoleon Bonaparte spent his last night there. It was from here that he learned that his coup attempt had failed and that he was leaving for Fontainebleau, from where he said his goodbyes.

In 1882, Camille Flammarion received this historic property from a generous admirer. The illustrious astronomer hastened to transform this old building into an observatory. He installed a 5-metre diameter dome to house the second amateur telescope of the time.

The place became a Mecca for scientific research. Passionate about all the natural sciences, Camille Flammarion set up a meteorological and radio culture station in the park. He built up a library of more than 10,000 volumes, rich in works on the history of science, by authors who are particularly sought after today, such as Copernicus, Tycho Brahe, Kepler, Galileo, Newton, Leibniz, Laplace and Delambre.

Famous people come to the observatory, such as the Brazilian emperor Dom Pedro II and the American astronomer Percival Lowel.
