Doune Castle is most famous for being the main filming location of "Monty Python and the Holy Grail". The audio tour, narrated by Terry Jones, combines both historical fact and tidbits about the movie production. Most, if not all, the rooms are open to the public, and you're encouraged to explore everything. I loved this place!
It commemorates Sir William Wallace. It's a tower standing on the summit of Abbey Craig, a hilltop near Stirling.
This cemetery is located under the Stirling Castle. Amazing.
