The Argonath, also known as the Gates of Argonath or Pillars of Kings, was a great monument of Gondor.
The monument was comprised of two enormous statues carved in the likenesses of Isildur and Anárion, standing upon either side of the River Anduin at the northern entrance to Nen Hithoel. It marked the northern border of Gondor, and nearby to the south were previous outposts, Amon Hen and Amon Lhaw.
