After leaving the modern city centre, we visited the Cathedral Metropolitana, the Plaza del Ayuntamiento, the central square of the old town with buildings of mixture architectural styles of Gothic, Romanesque, and baroque. The Cathedral is known for supposedly as the home of the Holy Grail from which Jesus shared communion with his chosen disciples at the Last Supper. I enjoyed this part of the tour as I was more interested in seeing historic churches, not the typical modern, sprawling and industrialized city centre.
My Spanish came in handy when I was not sure if I had to pay to use public restrooms. As I walked towards one of the toilets, a lady stopped me and she said "Un momento". So I said to her, "Dinero necesita?". She said no so I waited behind her. Turned out, she was waiting for her daughter. Almost 20 years later, two words I still remembered from my Spanish courses at Hunter College were put to practical usage!
