Mountain trolls

Mountain-trolls were a large type of Troll that were closely related to Cave-trolls and Hill-trolls. They were allies of Orcs.


Like all Trolls, Mountain-trolls originated from Morgoth's twisting and crossbreeding of other creatures of the world, and later became minions of Sauron.

Mountain trolls could be found in the mountains of Middle-earth. Their type helped move the great battering ram Grond into place during the Battle of the Pelennor Fields, which they wielded and shattered the large gates of Minas Tirith with. Members of the species also were seen opening the gates of the Black Gate.[1]

Physical appearance

Mountain-trolls were very large, larger than Hill-trolls, and had brownish skin.(Non-canon)


The Mountain-trolls make dangerous opponents in battle. These trolls are smarter than Cave-trolls, and their power to lift massive objects to use as weapons makes them deadly. They are assumed to be strong enough for other heavy tasks as well. They are stronger than cave trolls due to their harsh environment.(Non-canon)

Portrayal in adaptations

The Lord of the Rings film trilogy

Mountain-trolls were shown in Peter Jackson's The Return of the King film during the Siege of Gondor.
