Forannest was the northern gate of the Rammas Echor, the great encircling wall of the Pelennor Fields. It was located in the north-west part of the Rammas and the northern road from Minas Tirith ran through Forannest joining the Great West Road.
During the War of the Ring, Gandalf and Peregrin Took passed through the gate which was under the command of Ingold. Several days later the forces of Sauron coming from the Morannon, take Cair Andros and breach the Rammas Echor. Forannest was destroyed, and Ingold and his men were the last to retreat from the wall to Minas Tirith.
