Now completely uninhabited, this island fortress would make the perfect refuge from a Zombie attack, as it is surrounded by a particularly large moat: the Atlantic Ocean. Designed to repel the British, this fortress comes equipped with canon mounts and was once used as a prison, meaning it is pretty secure. So, if you find yourself stuck on a ship during the Zombie attack, why not head to Fort Boyard for a vacation from the undead.
Disregarding the fact that you would go to the closest shelter in the event of a zombie attack, which of these refuges would you like best? Link
