When the Ñoldor returned to Middle-earth, they built the tower/fortress of Minas Tirith to keep the enemy out of the West Beleriand. The pass was guarded by Orodreth of the House of Finarfin for his uncle Finrod who guarded it until FA 457, when it was conquered by Sauron. It remained in Sauron's hands until he was driven out by Lúthien and Huan in the mid-460s. Afterwards its defense was neglected.
