Tips from the Community

Jean-Michel PERTOLDI
January 8, 2023, Pont habité de Landerneau

The commune of LA ROCHE MAURICE located in the Pays du Léon reveals on a hill the ruins of its castle built in the 5th century which overlooks the Elon valley. Its history is linked to the counts of Léon and deserves to be known. The visit takes place at the foot of the ruins and the walker can see the efforts it took to build this castle currently under construction. If you want to know a little more, here is one of the sites which will immerse you in the history of the Roc'h Morvan castle (https://larochemaurice.fr/chateau). Good reading

The Elorn takes on a wilder face on leaving Landerneau, and resumes its sinuous aspect.

This bridge crossing the Elorn is one of the oldest in Europe. It is also one of the few still inhabited.

The Elorn flows under this bridge which has retained its medieval appearance. The alleys surrounding old Landerneau complete the picture.
