The Glittering Caves were located behind Helm's Deep under the three peaks of the Thrihyrne in the northwestern arm of the White Mountains. Gimli called the Glittering Caves one of the marvels of the Northern World. The Glittering Caves extended deep under the mountains, with many passages, stairs, halls, and chambers. The floors were sandy and the ceilings were high, domed vaults. The walls were polished stone set with gems and crystals and veins of ore.
As a Dwarven Colony
When Gimli Elf-friend was held up in the caves with Éomer and many other Men of Rohan during the Battle of the Hornburg, he was amazed by their beauty. After the War of the Ring he brought from Erebor part of Durin's folk and founded a colony in the caves, becoming the first Lord of the Glittering Caves.
The Glittering Caves are one of very few locations in Tolkien's work that are associated with a real place. They were inspired by the Cheddar Gorge and Caves in the southern English county of Somerset.
