Minas Anor - the Tower of the Sun - was established as a stronghold by Anarion, son of Elendil, and over time it became the greatest city in Gondor. As the threat from Mordor increased, the City was renamed Minas Tirith - the Tower of Guard. During the War of the Ring, Sauron's forces besieged Minas Tirith and the Battle of the Pelennor Fields was fought outside its walls. After the downfall of Sauron, Aragorn was crowned before the gates of Minas Tirith and the banner of the Kings of Gondor flew over the City once more.
