12. There’s An Armory Inside the Metropolitan Opera House

The spaces that support the Metropolitan Opera house productions are equally as impressive as the front of house spaces, but they go far beyond the backstage and side stage area. In fact, the Metropolitan Opera back of house goes down three levels below the stage, including C level which contains the rehearsal rooms along with 16,400 square feet of storage.

In addition, if you’ve been to the opera, you know there is often a lot of fighting going on. In the back of the house, there is an armory filled floor to ceiling with weapons of different types and eras. Here you’ll find swords, guns, cross bows, lances, and even a medieval wrecking ball.
