Minas Morgul

Minas Morgul was once sister-city to Minas Tirith, capital of Gondor in the realm of Middle Earth. However, Sauron reached out to this city and claimed it in a time of weak Gondor rule, and the city was corrupted by the Witch-King of Angmar and soon became one of his bastions. It was here that he unleashed an Orc army upon the Free Peoples, and Frodo walked past this city on his way to destroy the One Ring.

Later in the War of the Ring, Minas Morgul was liberated and the evil within perished. However, Gondor never reclaimed the city as it still had an evil aura which struck fear into the heart of any man, woman or child that went there. It was left to crumble and the Witch-King attempted to clean it up during his Plight following his defeat.
