If you travel to Arequipa you’ve to have a hat. It’s the second city on the world with more solar radiation (the first is Alexandria) this because it’s a valley in broad Atacama desert. To me is hard to endure the heat there, and the buildings are made of a white volcanic stone that could be a bit strong to the eyes. Centuries ago they were painted with reds, blues and yellows, but in this age they have no paint, to my taste that’s good because they look more classical.
I don’t say that it’s terrible the weather there, only that I am not used to such sunny context, it has great spots to go and I’ve some friends that I’d like to visit, but certainly I am foreign in a city inside my country with a remarkable but so different culture.
