Monsanto, Portugal
Monsanto, "The Sacred Mountain" is the stunning rock village of Portugal. Perched high atop a mountain bordering Spain, the village consists of rock houses sandwiched among the boulders. Over 2,000 years ago, after a shrine was erected on the peak of the mountain, people gathered and established homes there. The buildings are granite. Rather than breaking the boulders up, the villagers leave them as they are and build around them. 90 people are still living in Monsanto, in homes nestled among the rocks.
