Fauvettes Viaduct
Highlight • Bridge
Built in 1913 for the "Paris-Chartres" line, bombed in 1944, unused, closed, the viaduct was recently renovated for leisure. We see caving groups training there, as well as climbers who practice climbing on the pillars.

La Troche Quarry
Highlight • Climb
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.

Obelisk of Saint-Vrain
Highlight • Monument
This monument was not erected for the completion of work concerning the tracing of the Paris Meridian and the triangulation of Jacques de CASSINI (work continued by his son César-François for the determination of the geography of France).
However, it is nevertheless thought that the place where the obelisk is located could have been a point of one of the local secondary triangles, during the verification of the basic triangulation (1740-1744) in order to increase its precision. DUVAL DE L’EPINOIS being very sensitive to this work, this monument is therefore only a “memorial monument”.

The Old Bridge of Balizy, or the Templar Bridge, spans the Rouillon. Hidden in the heart of the Templar Woods, and surrounded by magnificent forest paths, it is a superb place for a mountain bike ride.

I am unable to judge whether this bridge is actually connected to the Knights Templar Order, as described in the highlight title (the exact name would be “Poor Knighthood of Christ and the Solomonic Temple in Jerusalem”). In this case it would have to go back to the 12th or 13th century.

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".

Disused railway bridge once used to connect Paris to Chartres, it is now open to the public. The views it offers over the Chevreuse valley and the forest of Bures-sur-Yvette are magnificent. Crossing it while running increases the beauty of the landscape tenfold.

Hello Radfahrer! Be careful on this route, the path along the Bièvres turns out to be forbidden to cyclists; Pedestrians or joggers will remind you of this with "you can't read the pictograms!?!" Guter Spaziergang!
