Bregan Hold was the ancestral hold of the dwarf clan Dûrgrimst Ingeitum. It was carved out of rock on a shoulder of Mount Thardûr. The city was made out of reddish granite. The hold itself was "a thick solid building" that rose five stories to an open bell tower. The bell tower contained a large, flameless lantern, known as the Gem of Sindri, that, during notable occasions or emergencies, could be used to illuminate the entire valley with a golden light. Around the hold were numerous outbuildings, including living quarters, stables, forges, and a church dedicated to Morgothal. Also, further around the hold were many farms and stone buildings where the dwarfs would work.
