The city's main street zigzagged up the eastern hill-face and through each of the gates and the central spur of rock. It led to the Citadel through the Seventh Gate on its eastern part. The White Tower, at the city's highest level with a commanding view of the lower vales of Anduin, stood in the Citadel, 700 feet higher than the surrounding plains, protected by the seventh and innermost wall atop the spur. Originally constructed by a king of yore, it is also known as the Tower of Ecthelion, the Steward of Gondor who had it re-built. The seat of the rulers of Gondor, the Kings and the Stewards, the tower stood tall, so that its pinnacle was some above the plain. The main doors of the tower faced east, onto the Court of the Fountain. Inside was the Tower Hall, the great throne-room where the Kings (or Stewards) held court. The Seeing-stone of Minas Anor, used by Denethor in "The Return of the King", rested in a secret chamber at the top of the Tower. There was a buttery of the Guards of the Citadel in the basement of the tower. Behind the tower, reached from the sixth level, was a saddle leading to the necropolis of the Kings and Stewards.
