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”.

A little history: the Mennecy sequoia avenue was planted in Villeroy park in 1887 at the request of the Darblay family, owner of the place. It is the second longest avenue in Europe: it is 800 meters long and has 134 trees aged around 140 years and reaching over 30 meters in height, with an average circumference of around 4 meters.

Tips from the Community
A towpath, or "chemin de halage," which runs alongside the river or canal, was an indispensable part of the transportation infrastructure in earlier times. Before ships could be propelled by motors, horses walked along the bank, pulling the vessel against the current. This was called "treideln," and that's how towpaths got their name, which has been passed down to this day. Where these paths, located directly on the riverbank, have been preserved, they are popular with hikers and cyclists.

It's a technical and driving pleasure, in X-Country or enduro (even if there is almost no difference in altitude).

In the past, this towpath was used to bring boats up against the current. Today, they are perfect gravel tracks for cycling fun! Enjoy the views of the Seine.

Superb alley of giant sequoias, quite unlikely in Ile-de-France.

Superb alley of giant sequoias planted in 1887. It is the 2nd longest alley of sequoias in Europe. With magnificent specimens over 4 m in diameter. Even if some wither due to parasites and lack of water.

Very nice path, quiet. Maybe a little complicated on a road tyre, but for all roads it's rolling

Louis DUVAL de l’EPINOY Marquis of Saint-Vrain from 1747 to 1769. He had the Obelisk erected in 1750 in homage to the work of Cassini who had developed a system of measurements allowing the creation of the geodesic map of France. Started in 1750, this map was completed in 1790.
