Oh i found that, laughed and kept looking... Heres a description of MT
"Minas Tirith was built on a hill with seven concentric tiers culminating in the Citadel at the summit. Each of the seven levels stood 100 ft (30 m) higher than the one below it, each surrounded by a white wall, with the exception of the wall of the First Circle, which was black."
"The seventh wall contained the Citadel with the white Tower of Ecthelion, which was 300 ft (91 m) high, so that its pinnacle was one thousand feet above the plain."
So that ones square, lol and not 1000 bricks high. The end.
