I was fortunate enough last week to spend Thursday/Friday in London filming for a new PBS show called "Secrets of Underground London" - it will be out next year. One of the great joys of a shoot is the access you have to sites that, under normal circumstances, you might not visit. Even better, you get to do so with no one else around.
One of the challenges with many of the recent archaeological sites in London is that exclusive deals have been signed with specific channels (yes, I am looking at you Mithraeum) but we spent a very happy morning at the Roman amphitheatre in London, about 30ft below the Guildhall Art Gallery.
The museum is a masterclass in how to make a limited site (only the eastern end of the amphitheatre has been uncovered) accessible and understandable. The curators have managed to give a real sense of the size and scale of the site.
On either side of the entrance into the arena, two antechambers have been uncovered, one is pictured below. There is still debate how these rooms were used, but I suspect that they did not have a single exclusive use: guardrooms from which soldiers could "encourage" combatants into the ring, waiting rooms for those about to go into the ring and as holding rooms for animals. I particularly liked the posthole in the bottom picture. It shows that there was access from the antechamber into the arena itself.
