Edoras was the capital city of Rohan. The city of Edoras was built on a hill in a valley of the White Mountains (Ered Nimrais) by Rohan's second King, Brego son of Eorl the Young.
Edoras was built at the end of the valley of Harrowdale, which lay under the great mountain Starkhorn. The river Snowbourn flowed past the city on its way west towards the Entwash. As Rohan consisted of mostly small villages and farmsteads, Edoras was the closest thing Rohan had to a city, and held the Golden Hall of Meduseld. It was here that Aragorn, Gimli, Legolas, and Gandalf met with King Théoden.
