The Argonath, also known as The Gates of Argonath or The Pillars of Kings, is a monument comprising 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, as nearby down south were previous outposts, the Amon Hen and the Amon Lhaw.
