Being surrounded by desert offers the village a natural deterrent against invasion, as few foreign powers would be willing to endure the sandstorms that surround Suna. Sunagakure itself lies in a fortified valley behind cliffs of rock, with passage in and out of the village restricted to a single cleft between two cliff faces, making the area very hard to attack from the ground. The buildings seem to be made from a combination of crystal and clay or stucco, which help keep the buildings cool and gives them a unique look.
