The earliest known moai mounted on the ahu is the one standing at the Tahai complex. On the other hand the last statue to be mounted on the platform on Easter Island is at Hanga Kioe. Originally, it was erected in the middle of the 17th century. Hanga Kioe consists of two separate ahu, but one of them contains only a small remainder of the statue it holds. Just a part of the torso has been recovered from the ocean shore when statue was re-erected.
