Fort National, Saint-Malo's Bloody Gem of France

Fort National, standing proudly in the picturesque city of Saint-Malo, France, hides a somewhat grisly past, chillingly fascinating. Originally known as Fort Royal, it's had several lives and served different purposes over time - a fortress, a lighthouse, and even a prison during WWII. But perhaps its darkest role was during the Middle Ages, when it served as a gruesome stage for public executions, under the seigniory of Saint Malo. Sounds like a scene out of a horror movie, doesn't it?
