story of The Bull of Minos, since it is in this palace where it was written that the labyrinth existed. Focusing on the architectural aspects of the Palace of Knossos, it was a combination of foundations that depended on the aspects of its walls for the dimensions of the rooms, staircases, porticos, and chambers. The palace was designed in such a fashion that the structure was laid out to surround the central court of the Minoans. Aesthetically speaking, the pillars along with the stone paved northern entrance gave the palace a look and feel that was unique to the Palace of Knossos. The space surrounding the court was covered with rooms and hallways, some of which were stacked on top of the lower levels of the palace being linked through multiple ramps and staircases. Others were built into a hill, as described by the site's excavator Arthur John Evans, "...The palace of Knossos is the most extensive and occupies several hills." On the east side of the court there was a grand staircase passing through the many levels of the palace, added for the royal residents. On the west side of the court, the throne room, a modest room with a ceiling some two meters high, can be found along with the frescoes that were decorating the walls of the hallways and storage rooms. Plumbing During the Minoan Era extensive waterways were built in order to protect the growing population. This system had two primary functions, first providing and distributing water, and secondly relocating sewage and stormwater. One of the defining aspects of the Minoan Era was the architectural feats of their waste management. The Minoans used technologies such as wells, cisterns, and aqueducts to manage their water supplies. Structural aspects of their buildings even played a part. Flat roofs and plentiful open courtyards were used for collecting water to be stored in cisterns. Significantly, the Minoans had water treatment devices. One such device seems to have been a porous clay pipe through which water was allowed to flow until clean. Columns For sustaining of the roof, some higher houses, especially the palaces, used columns made usually of Cupressus sempervirens, and sometimes of stone. One of the most notable Minoan contributions to architecture is their inverted column, wider at the top than the base (unlike most Greek columns, which are wider at the bottom to give an impression of height).
