I walked up the stairs from the Metro to immediately see the imposing Plaza de Toros. I met a lady there with a West Highland White terrier who LOVED attention... mine and the students waiting to enter the building. At the entry, I found out you could go inside but it was very expensive. Then the young man pointed out that I could get a senior's discount. Sold! First part of the tour in the vestibule where they explained a tradition where bull fighters can only pass through THAT gate if they earn it. The plaques on either side of the doors honour those elite fighters.
