It feels like Scotland, the nature is very green and the ruins of the castle make it a remarkable place.

The Château d'Alleuze is a medieval castle whose history dates back to the 12th century. Today, the ruins of the building are preserved in their destroyed state. Nearby is the Chapel of Saint-Illide, which was rebuilt after its destruction in the 15th century. Since 1927, the remains of the castle have been classified as a monument historique.

Superb view of the Garabit viaduct, allowing you to cross the Truyère gorges. This metal structure, created by Gustave Eiffel, is 565 meters long and rises to 122 meters above the water. It was at one time the “highest viaduct in the world”!

The Garabit Viaduct, built by Gustave Eiffel three years before the Eiffel Tower in Paris, is THE historical monument of Cantal! It is a railway viaduct 565 meters long and 122 meters high which made it possible to cross the Truyère on the line linking Neussargues to Béziers.
