Its arcade columns originally stood on a stylobate of three steps and now rise from the ground without bases.  Its upper story is finished with white and rose-colored marble and also contains a lace-like parapet of oriental cresting.  Among the notable features in its courtyard is a large dark green ornamental bronze well-head, but most notable are the facades which total approximately 500 feet in length and which were largely designed by the brothers Giovanni and Bartolomeo Buon. Its famous parts include the "paper door" and "giant's staircase" or Porta della Carta and Scala dei Giganti. Adjacent to it is a former prison known as the Piombi, which is separated from this structure by the Bridge of Sighs. Called the "central building of the world" by Ruskin in his book on the architecture of its city, For 10 points, name this structure once home to the rulers of Venice.
