Constructed in the mid-18th century, Fort de la Cité d’Alet was used as a German base during WWII. One of the bunkers now houses this memorial, which depicts St-Malo’s violent WWII history and liberation. It’s an evocative and moving place. (Courtesy of lonelyplanet.com)
I had to walk to this site to at least see it. It was about a mile from my hotel on a flat path along the inlet. The fort was on top of a hill but the views were certainly worth the climb.
I’m not positive but there were several round barricade-looking pieces scattered along the road and to me it looked like each one was hit several times with shells during WWII. What do you think?

Climbing to the top of the hill there was almost a 180-degree view of the water so it was a great spot for watching the sea, now and during all battles. There were two holes built into the walls for larger artillery and two authentic and rusted weapons.
Here is the most interesting information I found on the battles between Allies forces and the Germans. Wow!
