Pont Rouge on the Louis XIV Canal

Highlight • Bridge

Originally, the Red Bridge was built at the end of the 17th century, namely in the years 1685-1686 on the orders of Louis XIV as part of his vast project to build the Maintenon aqueduct entrusted to La Hire and Vauban. The goal of this project was to be able to transport the waters of the Eure from Pontgouin (located west of Maintenon) to the Palace of Versailles. It was from 1684 that studies were carried out by La Hire who discovered that the Eure was approximately 80 feet (27 m) higher than the castle at Pontgouin.
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.

Saint-Piat Mill

Highlight • Monument

The Moulin de Saint-Piat is a water mill located on the Eure and dating from the 11th century where it was once used for the production of flour and the extraction of oil. You can admire the architecture of the mill, which was extended in 1865, and enjoy the view of the river and the nearby church. The mill is also a good place for birdwatching, as you may be able to see herons, kingfishers and ducks along the water.

Lavoir de Soulaires

Highlight • Monument

Beautiful, recently renovated washhouse. Its water is supplied by a spring, not the river. It's a great place to take a break.

The cycle path along the eure is a place of tranquility, where it is good to stroll in the early morning.

Chartres Cathedral

Highlight • Religious Site

Chartres Cathedral was built between 1134 and 1260, thus becoming one of the first great Gothic cathedrals.

Over the centuries, the cathedral was adorned and decorated so well that it still constitutes an exceptional monument today.

Chartres Cathedral is a must-see, both for its stained glass windows, its overall architecture and its sculptures.

Guiperreux Toad Crossing

Highlight • Natural Monument

At the edge of this road a pond which forms with the forest which surrounds it a protected natural area.
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.
