Potosi is supposed to be the highest city of the world at an altitude of over 4000m. The city played an important role in Bolivian history because of the Cerro Rico, a hill that contains silver. When I arrived in Potosi Liberation Day celebrations were going on. I explored the city and by surprise I ended up in the room where Bolivian President Evo Morales was giving a speech to the Potosian people. I didn't understand much of his speech though.
The celebrations went on for 24 hours with parades through the streets of Potosi. Many groups of miners and social communities participated in the parades. Therefore it was not possible to go into the silver mines for a tour. I didn't feel sorry to miss out on this one. I felt privileged to witness the local Liberation Day festivities.
