I remember when all this was organ.
The organ had been totally removed, just leaving the support brackets and pieces
of wood. And looking at this picture, I’d never noticed the bricked up
archway to the right of the organ - I wonder where that went?
Looking at my original picture of the organ, it had wood paneling, further hiding this mystery door.
Consulting the map, it appears to be the original door out of the Chapel. The
one to its left, with the glass missing above it, is a modern addition.
The spectral fog of doom briefly joined me, and then eddied away again.
