Ancient Sites of Kokas are remains of pre-history sites where you can find drawings on canyons. These drawings show palms and animals which are still clear until now. These drawings on canyons locally known as Tapuraran, were made using natural materials in red color, similar to human blood. Therefore, the local community often calls them blood paintings. In several parts, you can find human bones, because ancestors of the local community did not bury dead bodies but placed them by the canyon, inside caves, capes, or under a big tree which was believed to be special or sacred.
