The Chateau, located in the town of Collioure, near the border with Spain, was for a longtime strategic position for whoever ruled the area and changed hands many times over the centuries.
While architecturally, it’s a bit of a hodge-podge of additions and upgrades that were aimed at keeping up with the evolutions in warfare, it has an illustrious history, not the least of which was a 17th century struggle that involved the Spanish and the French in which d’Artagnan (the real one, not the fictionalized version of it) and his musketeers were instrumental in taking the castle from the Spaniards.
It is a humongous fortress that gives one a comprehensive glimpse in the region’s complicated history.
