Robin and Marian (1976)

The French castle besieged incompetently by Robin (Sean Connery) at the beginning and then pillaged irrationally by a psychotic King Richard (Richard Harris) was in reality Villalonso Castle.

Richard pays the price for his blood thirst when an old man ‘throws’ an arrow into his neck, causing his death the following day during a party filmed in the Palacio de Capitania, which is now the General Archive building of Navarra in Pamplona.

Villalonso castle is not a one film location, the Dutch film maker Wilfried Minks having made a horror film there called The Birth of a Witch.
