Certainly a historically interesting fortification.

The fort dates back to the 19th century and takes its name from a rock that is said to look like a praying monk - an impressive backdrop in any case.

The short detour is worth it: the ocean view is magnificent. There's a bit of a lack of information on site, but it's definitely worth a look.

We had a great day of cycling and arrived in Châteauneuf-du-Faou. We carefully washed the bikes with a steam cleaner at a washing station and had a picnic near our accommodation. We actually wanted to go to the castle in the picture - but the day had been eventful. So we heard a lesson from the neighboring school that included a bagpipe performance. Unfortunately, due to a lack of video storage, I cannot show you this piece of music!

When Napoleon I noted the problems of defending the French coasts, he decided to implement a vast fortification program. Around a hundred standardized structures, called “model 1811 towers and redoubts”, will be built. One of them was raised in 1812 at Pointe des Espagnes. The point evolved according to the performance of the artillery and the fortifications were improved until the end of the 19th century. The model tower will remain unchanged until the German occupation. The Germans deployed numerous bunkers around the perimeters and leveled the fort's firing platform and deprived it of its parapets and bretèches. https://www.cestenfrance.fr/fort-de-la-pointe-des-Espagnes-1812/
