I tried my hardest to find the original link but kept coming to a website to book a vacation stay in one of the homes there... so here’s the Wiki Link for the lazy Reddies.
And for those who don’t want to even click the link; It is a Walled City that was founded in the 1st century B.C.
“The walled city had a long history of piracy, earning much wealth from local extortion and overseas adventures. In 1944, the Allies heavily bombarded Saint-Malo, mistaking it for a major enemy base. Today it is a popular tourist centre, with a ferry terminal serving Portsmouth, Weymouth, and Poole.”
All is very interesting!!
