Minas Anor is a fictional city from J.R.R. Tolkien's Middle-earth, known as the Tower of the Setting Sun. It was built by the Dúnedain in the Second Age as a watchtower to guard against threats from the east. Over time, it became a significant stronghold for the forces of good. Later, Minas Anor was renamed Minas Tirith, which means Tower of Guard. It served as the capital of Gondor and played a crucial role during the War of the Ring, particularly in the defense against Sauron's forces. The city is characterized by its white stone architecture and tiered levels.
