The floating islands of the Uros are a set of artificial habitable surfaces built from reeds, an aquatic plant that grows on the surface of Lake Titicaca. The islands stand on a portion of the surface of Lake Titicaca, superimposed on blocks of reed roots on which successive layers of reeds woven or intertwined into mats are laid. Its inhabitants, the Uros, are an ancestral people that are currently concentrated on the Collao plateau and in Peru on the floating islands located in the bay of Puno.
