Cathedral and Tunnel tour

I went to the Cathedral in Buenos Aires when walking around with Steve who came to visit for a couple of weeks. We had a walk round BA ending up at the Cathedral. As most Catholic Cathedrals its full of gold and statues but its is beautiful especially the alter. We also went on a tour of the tunnels. I was so excited as I knew there was a network of tunnels running round and underneath the city. I know sometimes they have been used by Cristina the president for dinners, galas, casinos etc. However when we went we could only see a tiny part of it. In the past the tunnels have been used for so many different reasons, shops, schools, transport, protection, meetings and politics. It would have been beautiful to see more but sadly all but 10 metres was closed to the public
