聖盔谷
Upstream from Edoras, deeper into Harrowdale, are the hamlets of Upbourn and Underharrow. At the head of Dunharrow (from Old English "Dûnhaerg", "the heathen fane on the hillside") is a refuge, Firienfeld, in the White Mountains. Aldburg, capital of the Eastfold, is the original settlement of Eorl the Young. The Hornburg, a major fortress guarding the western region, is in Helm's Deep, a valley in the White Mountains.
