Iron Mountains

The Iron Mountains or Ered Engrin were an immense mountain range in the north.

Of old the Iron Mountains connected the Blue Mountains (Ered Luin) of the West to the Red Mountains (Orocarni) of the East, but in the wars between the Valar and Melkor the mountain range was distorted.

Melkor's great fortresses of Angband and Utumno were built in the mountains. North of the range lay the Forodwaith, a region of ever-lasting cold.

After the War of Wrath the Iron Mountains were broken and disappeared for a great part of their length. Remnants of the range in the Third Age included the Mountains of Angmar in northern Eriador, as well as the Ered Mithrin and the Iron Hills of northern Wilderland.
