- Le Fort du Guesclin
As everything in Brittany, this place is also full of history. Romans, destroyed, fortress in 800s, destroyed, fortified castle built by Bertrand du Guesclin in 1100, destroyed in 1598, this one built in 1756... - Côte de granit rose
Every interesting rock has a name, I'm sure an interesting name was given to this one as well. This one is close to La Plage Saint Guirec. Update: it's called Napoleon's hat :-)
