Glittering Caves

The caverns behind Helm’s Deep

Map of the Glittering Caves

Also called Aglarond, the spectacular jewelled caverns that lay in the White Mountains behind Helm's Deep. Gimli Elf-friend was astonished by their beauty during the War of the Ring, and they were later colonised by the Dwarves of Erebor, with Gimli becoming Lord of the Glittering Caves.

The Glittering Caves is one of very few locations in Tolkien's work that we can associate with a real place. They were inspired by the caves of Cheddar Gorge, in the southern English county of Somerset.


Notes

1

Strictly, all we know about the source of the Deeping-stream is that it ran out of the Deeping-coomb, the deep valley into which the Glittering Caves opened. We know, however, that the caves were filled with pools and the sounds of water, so it is hard to escape the conclusion that the stream's source lay within them.
