Pont Rouge on the Louis XIV Canal
Highlight • Bridge
Maintenon was still to this day an intermittent residence of the king's court, and major work was undertaken, such as the digging of the grand canal passing under the aqueduct, the planting of the banks or the drawing of the castle park by Le Nôtre. .
You should know that until 1838, it is by this bridge that the entry into Maintenon was made. The legend attributes its name to the color of the uniform of the soldiers in charge of its guard.

Guiperreux Toad Crossing
Highlight • Natural Monument
Each year, during the thaw (roughly from February to April), a "toadstool" is installed on the road that runs along the pond.
But what is a toaddrome exactly? So, it is not a place where one could indulge in clandestine bets on toad races, but a device intended to prevent these poor beasts from being crushed by cars in crossing the road to breed and lay their eggs in the pond on the other side of the road.
Indeed, thousands of common toads, but also frogs and newts, begin their long prenuptial migrations around March each year. They go to the nearest pond or pond to breed. Once their duty is done, they leave the aquatic environment to return to their summering areas where they will spend most of their time feeding.
In order to avoid a carnage of amphibians on the road, a tarpaulin is planted 600m on each side of the road to block their passage. In various places a hole has been made in which a bucket is buried. By looking for a passage all along the tarpaulin, the toad will inevitably end up at the bottom of a bucket. Every morning, volunteers come to collect toads and other frogs and drop them off on the other side of the road.
