Westemnet

The Westemnet was the western plains of Rohan west of the river Entwash. It probably extended to the river Isen.

The most important of Rohan's settlements and fortifications lay to the south of the Westemnet, where the White Mountains rose up from the plain. Helm's Deep was among these, and to the south-east was the seat of the Lords of the Mark, Edoras itself.
