Nargothrond

   'The great underground fortress on the river Narog', founded by Finrod Felagund and destroyed by Glaurung; also the realm of Nargothrond extending east and west of Narog.

   -----

   The hidden fortress on the River Narog.

   The stronghold and realm of Finrod Felagund, founded by him on the model of the halls of Menegroth in Doriath.

   The stronghold of Nargothrond was carved into the rock beneath Taur-en-Faroth, and could only be approached by a narrow path along the high banks of the River Narog. No bridge was built across the river until late in its history. The citadel long lay hidden from Morgoth, and was ruled wisely for long years by Finrod. After he was lost in the Quest of the Silmaril, his brother Orodreth expelled the usurping sons of Fëanor, Celegorm and Curufin, and was lord in Nargothrond.

   The lands to the north of the citadel were considered part of its realm, and the people of Nargothrond kept unceasing watch on the grasslands to the north; the Talath Dirnen or Guarded Plain.

   When Túrin dwelt in Nargothrond, he persuaded the Elves who dwelt there to change their long policy of secrecy, and openly attack the servants of Morgoth. So the Dark Lord discovered the city's location, and sent out an army under Glaurung to sack and destroy it.

   The name means 'Halls of (the River) Narog'.
