Amon Lhaw lay on the eastern bank of the Anduin in the Emyn Muil, directly opposite Amon Hen upon the western bank. Between these peaks was the island of Tol Brandir.
Amon Lhaw was formerly within the northern borderlands of Gondor, to the extent that a high seat (possibly named the Seat of Hearing) was built there. It was one of the two watchtowers of the marchlands of Gondor. However, centuries before the War of the Ring; by then, it had fallen under the influence of Mordor.
