Probably in many places along the Alpine Himalayan mountain range, including Algerie, Italy, Greece, Turkey, Iran, Afghanistan, India, among others. These mountainous areas are usually heavily fractured by faults and the resulting rock blocks have been used for millennia to build walls. It's rather hard to say if rock availability is the only reason that drove people to build in a given place: usually major faults zones are eroded by rivers and form valleys. this places are preferable building sites because of water availability, easiness of transportation along the river, etc. (sorry for my English)

Further evidence that the site selection for Machu Picchu may not have been an accident: Similar analyses reveal other ancient Incan sites, including Ollantaytambo, Pisac, and Cusco were also built at the intersections of fault zones.
