Helm's Deep, named for Helm Hammerhand, was a fortified gorge in the White Mountains located below the Thrihyrne. It lay near the Westfold and was the location of the Hornburg. It was later made famous by the Battle of the Hornburg, a major battle of the War of the Ring.
The gorge narrowed from the north, with the cliffs on each side heightening until its southernmost point, where the fortress of the Hornburg and the source of the Deeping-stream lay. The Hornburg was built upon a great spur of rock which extended from the gorge's northern cliff, and from the fortress to the southern cliff was built the Deeping Wall. The earthen wall known as Helm's D**e spanned the width of the gorge, acting as a first defense of the fortress.
Behind the Hornburg was located the Glittering Caves, which were renowned for their beauty.
