St Malo is an old walled city on the French side of La Manche (the English Channel – for some reason the French don't call it that…)
St Malo at one time was notorious for being the home port for pirates and privateers.
The city got its name from a Welsh monk who came to Brittany in 538.
It was a self-declared independent republic for 4 years from 1590.
You can catch a ferry from St Malo to Portsmouth in the UK.
