The vast majority of large churches in France bear the title "Notre-Dame" (which in German corresponds to the – much rarer – "Unserer Lieben Frau"). The patronage of this house of worship in the historic center of Marmande, and thus the corresponding parish community, has therefore been entrusted to Mary. The church itself is architecturally in the transition period from Romanesque to Gothic.

The Notre-Dame-de-l’Assomption church of Casteljaloux is a former collegiate church located in the heart of the town. A first Gothic church, built in the 15th century, housed a chapter of canons at the time. Destroyed in 1568 during the Wars of Religion, it was rebuilt from the 1680s onwards on its original foundations and according to the same plan, before being completed in 1763. Restored several times in the 19th century, it has a rare peculiarity: the motto of the Republic "Liberté, Égalité, Fraternité" appears on its pediment, added during work partly financed by the State in 1899. The building has been listed as a Historic Monument since 1998.

The lake of Clarens and its leisure center offer an ideal space during the warm season to enjoy the body of water. It's an ideal stop to cool off after a bike tour!

Lake Clarens is a very picturesque lake surrounded by trees. From the road you can see the trees reflected in the water for a nice photo. There are also picnic benches near the road.

The section marked here will be accessible in June 2023. Already completely finished from Casteljaloux, including signage, bollards and road markings. In the last few kilometers before the current end, there are still provisional “concrete Lego bricks” at the intersections with car roads. Work is currently underway on the further section to Marmande. Completion will not take long.
