One of the "highlights" in Cusco is the famous 12-edged stone. It is considered a symbol for the genuine craftsmanship of the Incas, because the stone is huge, but still it had been fitted perfectly into the wall construction. By the way, Inca buildings are earthquake-proof in comparison to many of the (much younger) colonial churches, that were destroyed during the frequent tremours in the region. However, the city center had always been rebuilt the traditional style, that is to say only low brick buildings and no skyscrapers. One reason why we loved that place. The siesta seems to last all day sometimes, but after sunset the city comes to life! Every night we watched another beautiful festivity on the main square and enjoyed a Cusqueña, our favourite Peruvian beer. We stayed in Cusco for 6 days, but we could have extended it to 100 days easily! There is just too much to do and see.
