Nice place to cool off on a small pebble beach just before the bridge when it's a heatwave!

Not long, it's flat along a small irrigation canal, shaded, educational information panels, particularly on geology, recommended with young children

The small rest area created here, with its very unusual design, invites passersby not to roll by carelessly: Behind the backrest of the bench rises a remarkable piece of craftsmanship: on one side, a flower stem bearing an unfolded blossom; and from the other, a bee flies towards it. An original idea, and rightly documented here several times with photos.

Here we encounter three stone cubes stacked on top of each other, each smaller than the one below it. The gray cubes each have a white field in the center of their sides, with a cross carved into it, painted blue and standing out against the gray/white background. This construction forms the basis for the present small sacred monument: above it rises a radiant gold figure of the Madonna. From this prominent position, the Virgin Mary – venerated in France almost always under the title "Notre-Dame" ("Our Lady") – gazes far into the country, and has done so for more than 120 years. @Rainer N. has already explained the date and reason for its construction in his short post.
