Salisbury cathedral.

We're now back home, but had a good look round the above, partly to see The Magna Carta (or one of the several contemporaneous copies of it, I'm not sure.) It was very dimly lit, and no photography was allowed athough, assuming it wouldn't be with a flash, I couldn't see why. 
The main is a font, added in 2008. I liked the reflection, and smooth dark water.
The spire dates from the early 1300's, and some of the original scaffolding is still in place. "We'll be back Thursday week" applied even then.
Extra 1: Part of the ceiling. A free roll of Agfa to the first blipper to spot a delicate wire Anthony Gormley figure.
Extra 2: An exterior view.
