This is the "back" of the Marae Aho-o-Mahine, one of the largest and most respected ancient religious site on Moorea. The marea are rectangles paved with rock, with a low wall surrounding the paved area, and for the more significant ones these "tiered" areas in the back which were the dias for the more important members of the clans. Notice the fresh leighs on the dias, recent offerings, showing some continuing reliance on the traditional religion.
