This is the closest I've got to Raiders, I must say. There's a whole load of ramshackle stairs to navigate - the unsafe ones are taped off, but... My colleague quite rightly asked how the decision to call a stair 'unsafe' is made? I had to reply that I supposed it was when something broke during a visit. She wasn't very reassured, and we were both glad to get back down to terra firma.

Needles to say, we have a very comprehensive risk assessment. And I always tell my crew that if they don't like the look of something, don't do it. There's no use risking life and limb for archaeology.
