"Immeasurable halls, filled with an everlasting music of water that tinkles into pools, as fair as Kheled-zâram in the starlight"
The Two Towers, Book Three, Chapter VIII: "The Road to Isengard"

The Glittering Caves, also known as Aglarond, was the cave system located behind the Deeping Wall of Helm's Deep.


The Glittering Caves was an immense, beautiful, and ore-laden cave system that extended deep down into the White Mountains for many miles and consisted of many different paths, tunnels, and chambers. A small stream ran down through the narrows of Helm's Deep and into the caves and was its source of water.


Before the War of the Ring

The Glittering Caves were little used, explored or known of outside Rohan, with the Rohirrim using them as a refuge during war and the storage of provisions.

War of the Ring and afterwards

During the War of the Ring, the Hornburg was the refuge of the Rohirrim in the Battle of the Hornburg after being driven back by the Host of Saruman.[1]

After the war, Gimli the Dwarf, who had fought mightily in that battle, was allowed to settle a colony of Durin's Folk in the Caves, leading a host of Dwarves from the Lonely Mountain and became the first Lord of the Glittering Caves. Gimli and Legolas had made a pact of friendship that when the War of the Ring ended, Gimli should walk in the deep woods of Fangorn and that Legolas should behold the jeweled splendour of the Glittering Caves. Gimli did so, and in time the Dwarves of the Glittering Caves restored and strengthened the Hornburg.


In Sindarin, the caves were called Aglarond, meaning "Caves of Glory" or "Caves of Light". It comes from the words aglar ("glory, light") and rond ("cave").[2][3] It was called Glæmscrafu, the "Caves of Radiance", in Rohirric, which in actuality was an Anglo-Saxon word.[4]

Behind the scenes

The Glittering Caves is one of the very few locations in Tolkien's work that can be associated with a real place. They were inspired by the caves of Cheddar Gorge, in the southern English county of Somerset.[5]
