Built in the 1800s, this location was redeveloped and outfitted at some point only last century with a 'modern' heating system.
I had read a lot about the history of this building and was determined to find out what it had to offer. I took backstage tours and sauntered about the foyer before shows started. After weeks of sussing it out, I found my way in.
All I needed to do was wait until the gent's bathrooms were empty, slide an access panel aside that was located inside a cubicle and above a toilet cistern and start crawling. The gap was very small but only for a couple of metres. After that, this place was mine to roam free.
Just beyond the brick walkway pictured below was a set of concrete stairs that took me up to a face-sized grille where I perched myself for all of Les Pȇcheurs de Perles' three acts, able to watch the performance from an unorthodox but refreshing angle.
