Our Lady of Peace is the administrative capital of Bolivia and the highest capital in the world! The colonial city that is at the heart of the present city, is lower than other neighborhoods. The streets are much like those of other colonial cities in South America. But because of its mountainous topology, here it was harder to organize the city into blocks that were perpendicular, as in Mexico or Chile . The streets are crooked, winding, go up and down and the air becomes increasingly difficult to breathe. It is a cheap place where you can sleep for 3 euros per night, eating for 1 euro and most visits require no payment.
