Holy Grail Castle.

Puyvert Chateau in France is where the actual Grail Precession took place. Shown here is the actual ruins, not the modern addition abutted onto the east wall, where in the top right corner is the Great Hall where Perceval sat in company of the Fisher King (circa 45AD) watching the Grail going room from room and passing before them. Surprisingly, the fireplace also still remains for visitors to see. Puyvert translates to 'green place'.

The 'mighty' Grail Castle is in the high Pyrenees Mountains and is not Montsegur - a hoax promoted by gay Nazi Otto Rahn when the locals were making a fool out of him!
