The Dwarves of Belegost are efficient miners and highly skilled builders. They have build the largest Kingdom in the Ered Luin and with their kin in Nogrod, they helped the construction of the capital of Doriath - Menegroth.

–Quenta Silmarillion, Of the Sindar
Belegost, Great City in Sindarin, is one of the two dwarven cities west of the Ered Luin. It was founded by the Broadbeams and Firebeards, presumably in the Years of the Trees.
The people of Belegost, along with their kin in Nogrod, helped in the construction of Menegroth, the Thousand Caves. In return, they were given pearls found in the shallow waters of the Bay of Balar. Even though these pearls were found aplenty in those waters, the Dwarves had never seen their like and valued them above all else.
Belegost is ruled by Azaghâl, son of Gorlin, who is known to be a formidable warrior, hence his name.
