Sauron's Road

Sauron's Road is a road leading from Barad-dûr to the Sammath Naur inside Orodruin.

It leaves the great iron bridge at the Dark Tower proceeding across Gorgoroth through a chasm in the mountain and then up a long causeway to the door to the Sammath Naur.

History
It was probably created in the late sixteenth century of the Second Age when Sauron sought to control the other rings by creating the One Ring, using it as an easy way to get to and from the mountain during his labors. Over the long ages it was frequently blocked and ruined by the ravages of the erupting volcano, but it was always repaired. Frodo and Sam used part of this road to get up the mountain during their quest to destroy the ring.
