The pictures of Castle Stalker (in Loch Laich, Appin Scotland; the castle of Monty Python fame…) were found here

The Castle Aargh! near the end of Monty Python and the Holy Grail, is Castle Stalker, in Loch Laich, Scotland.

I recommend the movie*, but only if you’re in a silly mood.

*the movie may lead to a fear of rabbits.
