Estimates for today's mass are around a million. I watched it on TV, since I didn't feel like getting up in the pre-dawn to get a good seat. All of Colon was filled, and the streets radiating from it, including Castellana and Recoletos, had seating too. They closed down Castellana from Glorieta Emilio Castelar south. In the afternoon, I took a walk down the median of Castellana (!) to check out the huge operation that is required to do a papal visit. I'm not Catholic, but the mass was moving nonetheless, especially given the Pope's waning health.
