Grond (battering ram)
Grond was a battering ram, used by Sauron's forces to destroy the Great Gate of Minas Tirith during the Battle of the Pelennor Fields.
Grond means "mace" in Sindarin. It was named intentionally to evoke the memory of the ancient weapon of Morgoth, the "Hammer of the Underworld".
2003: Peter Jackson's The Return of the King:
- The ram took the shape of the whole wolf's body, rather of just its head. Gothmog called it in after a smaller battering ram proved futile against the great gates.
