tank scenes.

We were taken to the tank where all the underwater scenes are filmed. We went downstairs and there was a large window looking into the tank. It is the deepest tank in Europe and the smell of chlorine stung my eyes. The water was bath temperature and there were scaffolding towers inside the tank. Next to it there were a row of wetsuits and breathing apparatus. The scenes in the cave with Dumbledore and Harry were filmed here.
