Yeah, good telly overall. Maeshowe always makes good viewing (check out the Drude's own take on it via YouTube) and I never tire of hearing how much older and more important the antiquities of the northern islands are compared to the over-exposed (but still wonderful, mind) Stonehenge.

The rock-climbing bit was indeed unnecessary though - and the guy's achievement in climbing that stack was pretty much cancelled out by the cameramen who'd clearly beaten him to it!
