Sammath Naur

Dark cavernous chambers deep inside Mount Doom containing the fiery fissure known as the Crack of Doom. Site where Frodo claims the Ring and it is ultimately destroyed.

Sammath Naur, the Chambers of Fire deep within Mount Doom, stands as the ominous heart of Sauron's realm in The Lord of the Rings, a cavernous forge where the One Ring was originally crafted amid rivers of molten rock. It emerges prominently in the series' climax as the fateful destination for Frodo and Sam's quest, embodying the ultimate test of will against the Ring's corrupting power. Though unmentioned in earlier volumes, its singular role in The Return of the King cements it as the pivotal site of the Ring's destruction, toppling Sauron's dominion in a cataclysmic eruption.
