To the north of the great height of Mount Dolmed was Gabilgathol, which the Elves interpreted in their tongue Belegost, that is Mickleburg; and southward was delved Tumunzahar, by the Elves named Nogrod, the Hollowbold.
- The Silmarillion, Chapter 10
Once looming over the only known path from Beleriand to Eriador, Mount Dolmed is a mountain on the western edge of the Ered Luin. Some of the first dwarves founded the cities of Belegost and Nogrod east of the mountain in the Years of the Trees. Like much of the Ered Luin, it was heavily damaged in the drowning of Beleriand.
