This morning, I took a taxi to Avenue July 9 where Teatro ColÃ³n is. I took a guided tour throughout this impressive opera house and learned about its construction, history, and shows. We went into one of the boxes to view the stage, and there are two boxes right next to the stage that are reserved only for the President and the other only for the Mayor. They will remain empty if they donÂ´t attend the show. Beneath the opera house was a massive area full of rehearsal rooms, stage construction, seamstress rooms for costumes, ballet halls for practice and more. It was a great tour!
