:40 turns out to be Edinburgh Castle?
Definitely not Edinburgh Castle, that has a far greater fortification than the castle in the intro - I'm inclined to say it's more likely a castle in Belfast. So far, we can rule out Belfast Castle and Carrickfergus Castle (although that's not 100% out of reach, I just couldn't find a half-decent picture). At :42, there seems to be a cemetery, which I think might be Edinburgh Cemetery, as a lot of Scottish tombstones include the skull and crossbones on them. Alternatively, it could be Greyfriars Kirk, but I am leaning more towards Edinburgh Cemetery.
(Sorry the actual pic of Edinburgh Castle is considerably smaller than the others, I just used an already resized picture from my Pic library).
