It’s a bridge (Pont Barré) over the river Layon, built in XI century, restored in 1988.
The river Layon, was sort of a frontier between the region Anjou and Poitou. The bridge Barré was a demarcation point between Republicans and Royalists during the Vendée War (1793).
As at those days, the tax of salt was higher in Anjou then in Poitou. there were farm soldiers on the bridge controlled the traffic of salt between these two regions.
There are vineyards around the valley Layon, a very good white vin Coteau de Layon is from here.

Let the Images Speak 
looks to be
a peaceful
bridge, now 🙂
No more control 🙂
Wonderful photos and history lessons. I listened to a whole podcast once about how salt was one of the most valuable commodities in the days before refrigeration, as a food preserver. So I get why a war would have been fought about. Neat, the connection with this humble little bridge.
I didn’t think between salt and refrigeration, but of cours! Today we all have frige but still use salt as preservative (fermented vegetable, salted meat, salted fish …), how important salt was and still is, and how we can learn history from a little bridge. Thank you so much for your comment.
Thanks for the photo tour!
My pleasure!
