One time I went to a choral concert and was delighted with the place and its acoustics, but the most magical experience was once, during the week, I went through one of the side streets of the Colon and found an open door that opened onto a wide hall. I entered, out of curiosity and climbed a side staircase that took me to the entrance hall. Rarely was there anyone to guard. When I turned, the central entrance of the stalls was open. I entered and walked calmly until the beginning of the audience, almost to the stage. I turned around and I could appreciate the majesty of the place in the silence. I was very impressed and it was an unforgettable short experience. When they can go to the Colon. I think there are guided tours. Safety pin!!
