Upbourn was a hamlet located in Rohan, south of Edoras on the banks of the Snowbourn in the valley of Harrowdale. Upbourn was one of the small villages that lay in the White Mountains, in the valley of the River Snowbourn known as Harrowdale. This placed it close to Rohan's capital of Edoras, and indeed it was on the road between Edoras and the mountain refuge of Dunharrow. Thus Théoden and his armies of Rohirrim passed through Upbourn during the War of the Ring, at the beginning of the journey that would lead them east to the Battle of the Pelennor Fields.[citation needed]
