Underneath the famous Teatro Colon is a factory of expert artisans creating the props and costumes that they use on stage. Since it's a working factory, it makes sense that these workshops are not part of the tour.

Thankfully, they now put these works of art on display in La Boca at Colón Fábrica. If you're at all interested in theater then this is a must visit museum just steps from the Caminito.
