A medieval fortress originally built in the 12th century and reconstructed multiple times throughout its turbulent history. The castle was demolished in 1395 by the Duke of Brittany due to its owner's rebellion, then rebuilt in 1406, and partially dismantled again in 1626 on Richelieu's orders after another conspiracy. The fortress features impressive defensive architecture including a barbican, gatehouse with 6-8 meter thick walls, and two major towers - the Tour de Rougé and Tour d'Acigné - both over 20 meters high.

The wooden ceiling with the cross beams is particularly noteworthy in this church. It is very beautiful, partly painted. The baptismal font has a lid in the shape of a scallop shell, which could refer to the Way of St. James. As a whole, it seems wider than it is tall and therefore different from many cathedrals we have seen.

The original Marian shrine "La Salette", which is referred to here, is located in the French Alps (Grenoble district) and is an important Marian shrine, even if it is nowhere near as well known as other pilgrimage sites in honor of the Mother of God - such as Lourdes in the French Pyrenees or Fatima in Portugal. The hiking highlight "La Salette" can be found in komoot at the following link: https://www.komoot.com/de-de/highlight/1861054

The Léguer is a 59 kilometer river. It only crosses two towns, including Lannion. Populated by Atlantic salmon, European otters and many other species, it is labeled “Site Rivières Sauvages”. It is therefore a vein of blue gold which crosses the beautiful town of Lannion. It takes its source at a place called “Pen Léguer” and flows into the sea at the Bay of Lannion. From the banks of the Léguer in Lannion, you can see the leisure center, the former Saint-Anne convent and the park of the same name.
