The “Petit Launay” oak (the aulnoye), remarkable for its size and the distribution of its branches, seems to date back to the 15th century. The organizers of the Universal Exhibition of 1900 in Paris wanted to transport it to the capital, which attests to the interest that this Tree already presented. Mr Grisier, mayor of Bures and owner of “Petit Launay” fortunately declined this offer. This estate, a former stronghold from the 14th century, has been better known, since 1810, under the name of "The Virgin". A statuette is still visible on the surrounding wall of the property. It is crossed by the Vaularon, a tributary of the Yvette, hence the humidity conducive to the growth of alders. This tree has been classified in the list of “venerable trees in France”.

Listed among the major geological sites since 2007, this former sandstone quarry offers a nice setting for running between rock and sand. The hue of the stone also earns it the name "Blue Rocks".

The 3 cellars of Sermaise constitute the most important Essonne site for the hibernation of chiroptera. Indeed 6 different species of bats have been observed

Site steeped in history converted into a climbing and relaxation site (landscaped trails, picnic tables). To find out more about the old quarry: http://photos.piganl.net/2018/troche/troche.php

A super romantic little bridge. Certainly perfect for a marriage proposal during a sporting outing in the Chevreuse valley.

The Troche quarry is today located in the very heart of the Eugène Chanlon Municipal Park, in Orsay-Palaiseau, in the Lozère (Palaiseau) district. This is an old sandstone quarry, traces of which can be found on the edge of the Saclay plateau, where a whole plateau of industries is currently located. All that remains of the quarry today is the working face, 5 meters high and approximately 200 meters long. Today it is only used by rock climbing enthusiasts. In the lower part, approximately in the center, you can see a Romanesque window... but it actually only dates from 2004! A little history The exploitation of this quarry has been documented since 1720. It was mentioned in Napoleon's land registers in 1809. At the end of the 19th century, the quarry was owned by the Pigeon family, and employed 25 to 30 workers. Work was interrupted at harvest time because the quarrymen, very often, were also agricultural workers. "The production was intended for Paris, brought down twice a day to Lozère station from 1867 by carts pulled by 3 horses, loaded with 120 paving stones (around 2 tonnes), and transferred to wagons using an additional track for goods (1891).” “Before the railway, it took two days round trip for a cart to reach Paris” The quarry closed its doors in 1937, and today it is more than a souvenir that can be discovered inside Eugène Chanlon Park. The stone extracted from this quarry is sandstone. These so-called Fontainebleau sandstone and sand banks were formed in the Quaternary era (Stampian period) around 30 million years ago.
