Nogrod was one of two great underground Dwarven cities in the Ered Luin, the other being Belegost, that prospered during the First Age. It was home to the Dwarves of Nogrod.
Geography
Nogrod was delved in the eastern side of the north-central part and of the Blue Mountains southeast of Mount Dolmed where the Dwarf-road of Beleriand crossed into Eriador, guarding one of the only passes over the Blue Mountains not far from lake Nenuial.
The city was built sometime during the Years of the Trees when the western Fathers of the Dwarves awoke from beneath the Ered Luin.
Nogrod traded throughout Beleriand and the Dwarves were employed for delvings and crafts, most famously the Nauglamir for King Thingol. Eöl the Dark Elf often went there, as did his son Maeglin.
At the end of the First Age, Nogrod was ruined in the War of Wrath, and around the fortieth year of the Second Age the Dwarves of the Blue Mountains began to migrate to Khazad-dûm, abandoning Nogrod and Belegost. However, there always remained some Dwarves on the eastern side of the Blue Mountains in days afterwards.
