Tamar Frank worked on the underground corridorways around the gunpowder room with fosforescent pigment. As soon as the visitor has descended the light goes off leaving behind an eary glow in the dark space. It has an hallucinating effect and the walls seem to come alive in some places. The oppressive feeling of an underground hide-out is explicitely sensed here.
