Nardol

The Beacon on Eilenach was the second out from Minas Tirith, but the summit of that mountain came to a sharp point, making the building of a bright beacon difficult. The next Beacon site to the west was not so hampered - it stood on the broad end of a ridge of the White Mountains, and the guard station maintained there could create a huge signal fire when needed. It was for this reason that the third Beacon acquired the name Nardol, 'fire-hilltop' (S. naur "fire" + dôl "hill"), because its beacon-fire was so bright it could be seen more than a hundred miles away.
