Rohan is a grassland that lies north-west of Gondor and Mordor. This realm is inhabited by the Rohirrim, a people of herdsmen and farmers who are known for their cavalry. Rohirrim is Sinfarin for People of the Horse-Lords. Rohan is also referred to as Riddermark or the Mark. The countryside of Rohan is a land of pastures with a lush tall grassland. Rohan's climate brings hot summers and brisk short winters, being near the center of Middle-Earth, the winds and air masses can come from almost any direction and the weather is highly variable in season. The capital of Rohan is the hill fort of Edoras which is on a hill in the valley of the White Mountains. The city of Edoras was built by Rohan's second King, Brego son of Eorl the Young. The city is protected by a high wall of timber, and a one-way road into the city. Rohan plays a big role in The Lord of the Rings as does its people.
