From the BBC website:

Knights, cardinals and bearded ladies have been swarming round the grounds of Doune Castle as fans marked the third annual Monty Python Day.

Built by Robert Stewart in the 14th Century, the keep appeared as Castle Anthrax in the 1975 film Monty Python and the Holy Grail.

Since then, thousands of devout fans have made their way to the castle, outside Stirling.
