Calocour Heights was a marketing district in the Senate District of Coruscant's Galactic City. It was located between the Palace of the Republic, which was to the south, and the Senate Building. It was near Column Commons. When Coruscant fell to the Yuuzhan Vong during their invasion of the galaxy, Calocour Heights was one of the areas destroyed in the battle. As Coruscant was terraformed to become Yuuzhan'tar, the area was razed, and the Heights were replaced by the Square of Hierarchy.
