The ramparts protect the entirety of the old part of Saint-Malo and from a circuit of 1.75 kilometres.
They were started in the 1100s, updated to combat new military technology in the 1600s and then expanded again up to the mid-18th century.
When you do the walk be sure to have some literature with you, because every gate, bastion and view has a story to tell.
Go up for panoramas of the sea, the Grand Bé island, Fort National, Dinard across the water and the magnificent granite homes of the city’s wealthy ship-owners, and come down if you see a shop or crêperie that takes your fancy.
Grande’Porte on the eastern side is flanked by two chunky bastions and guards the narrow finger of land that links the walled city what are now Saint-Malo’s suburbs.
