The capital, Minas Tirith, lay at the eastern end of the White Mountains, built around a shoulder of Mount Mindolluin. It had seven walls, the gates facing alternately somewhat north or south, so the main street up to the citadel wound in zigzags up the hill, each time passing through a tunnel in the central spur of rock. In the citadel, atop the spur, were the Court of the Fountain with the White Tree and the White Tower. This was the seat of the Kings or Stewards of Gondor. Behind the tower, reached from the sixth level, was a saddle leading to the necropolis of the Kings and Stewards. Tolkien's map-notes for the illustrator Pauline Baynes indicate that the city had the latitude of Ravenna, a city on the Mediterranean sea, though it lay 900 miles east of Hobbiton more near Belgrade. The Warning beacons of Gondor were atop a line of foothills running back west from Minas Tirith towards Rohan.
