The Pelennor Fields were the townlands and fields of Minas Tirith, capital of Gondor, a large, grassy, open plain between the river Anduin and Mount Mindolluin.

After Minas Ithil had fallen and was renamed Minas Morgul, the Pelennor Fields were walled by the great wall of Rammas Echor to prevent an invasion.

The name Pelennor meant Fenced Land in Sindarin.

During the War of the Ring, the Pelennor Fields were the location of the Battle of the Pelennor Fields, when Sauron's orcs and evil men overran the Rammas Echor and besieged the city.

It was on these fields that Théoden King was slain, along with the Witch-king of Angmar, and that most of the

great battle was fought. After the War of the Ring, the Rammas Echor was rebuilt by the dwarves of Aglarond.
