Transfer from the hotel in Arequipa at 08:00 am to continue to the Culebrillas quarries (3km from the center of Arequipa), which are mainly located in the district of Cerro Colorado and Yura. After the earthquake in Arequipa in 1687 there was a massive use of the construction system with Sillar, and when it was perfected, the beautiful colonial architecture of Arequipeña resulted. The quarries of Sillar come from the eruptions and in the tour we will be able to appreciate the cutters of this stone in their daily tasks, as well as some samples of carvings. In this place we can see where the masons take Ignimbrite and then patiently develop the Sillar, they will explain in detail the preparation there and we will also learn the story behind the Sillar. We return to the city of Arequipa around 12pm and transfer to the hotel in Arequipa.
