Ered Engrin ARDA

Location of the Iron Mountains in Arda.

The Iron Mountains, also known as Ered Engrin, and the Mountains of Iron were an immense mountain range in the northern part of Middle-earth.

The Iron Mountains have always been associated with bitterly cold climates[1] partly due to the influence of the evil Kingdom of Melkor. It was also the former location of his ancient fortresses of Utumno and Angband.[2][3]


After returning to Arda from the Outer Darkness with his allies through the Door of Night, he created the Iron Mountains and behind these walls safe from the light of the northern lamp Illuin he delved the great fortress of Utumno. Angband was also delved into these mountains west of Utumno. After Melkor's destruction of the Two Lamps, the Iron Mountains were connected to the Blue Mountains of the West to the Orocarni of the east.[2][3] Much later when the Valar decided to protect the Elves from Melkor by defeating him and imprisoning him, the changing of the shape of Middle-earth effected the Iron Mountains as well. Afterwards, the mountain range was distorted but was still long with lengths stretching from the Helcaraxë in the far northwest to the Orocarni in the far east and rising to immense and frighting heights, with enormous peaks such as Thangorodrim.[4] [3][5]

In the days of the War of the Jewels, the mountains protected Morgoth from being outflanked from the rear and with no enemy behind him, he was able to concentrate on the south. Because of its perilous heights, frightening looks, and foul winds, no Elf ever passed through the mountains for any reason but the spies of Morgoth would always find ways into the Beleriand, by unknown ways through the mountains. Morgoth's forces also captured Elves and brought them through the mountains to Angband.[6]

After the War of Wrath the Iron Mountains and Thangorodrim were destroyed and the vast mountain chain was broken and disappeared for a great part of their length. North of the range lay the Forodwaith, a region of ever-lasting cold. Remnants of the great mountain 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 Rhovanion.[7] The Iron Mountains remained unchanged after the Change of the World and ever after.[8][9] The only people known to have lived in the cold climates of the Forodwaith were a Mannish people known as the Lossoth, the descendants of the people known as the Forodwaith who once lived in the area around the Iron Mountains of the Ice-Bay of Forochel.[10]


The Iron Mountains was known as the 'Ered Engrin' in Sindarin which meant 'Mountains of Iron'.[11]
