Nogrod was one of two Dwarven cities in the Ered Luin.
Nogrod lay in the middle of the mountain range, near Mount Dolmed where the Dwarf-road of Beleriand crossed into Eriador.
It was home to the Dwarven House known as the Firebeards. Its name in Khuzdul was Tumunzahar of unknown meaning. Nogrod translates as "Hollowbold".
Nogrod was home to the great Dwarven smiths Gamil Zirak and Telchar. Eöl the Dark Elf often went there, as did his son Maeglin.
While initially friendly to the Elves of Beleriand, the Dwarves of Nogrod killed Thingol of Doriath in his treasury after having grafted the treasure of Nargothrond for him, and they returned to sack the city after the departure of Melian and her protective Girdle of Melian.
They were hunted down by Beren Erchamion and killed by his army of Laiquendi and a group of Ents.
Unlike Belegost to the south, Nogrod was utterly destroyed during the War of Wrath, when the Blue Mountains were broken and the Gulf of Lune flowed into Eriador.
