- It is the first of the northern line of the Warning beacons of Gondor (directed towards Rohan), being the closest to Minas Tirith.
- North and west from Minas Tirith, a low-lying chain of hills ran through the Drúadan Forest, Taur Drúadan, in parallel with the easternmost White Mountains. East of the forest, the last of these hills rose to form a great isolated height north of the Grey Wood and Mount Mindolluin. This was Amon Dîn, the so-called 'Silent Hill'.
- To a traveller passing north along the road from Minas Tirith, Amon Dîn would rise to the left after some forty miles. With a wide view of Anórien, Cair Andros and North Ithilien across the Great River, it was natural that the Gondorians should make it a guard post, and indeed it was fortified from early in Gondor's history.
- At some point the camp on Amon Dîn was equipped with a beacon. This was the first of a series of beacons to call for aid from the Rohirrim. After that on Amon Dîn, beacons were built on Eilenach and Min-Rimmon and more beacons were added as the years passed. At the end of the Third Age, a line of seven beacons stretched from Amon Dîn as far west as the Halifirien on the borders of Rohan.
