A large part of the east wing cannot be seen from the Central Court as it is built into the side of the hill on top of which lies the rest of the Palace. It is one of the most interesting parts of the palace because two storeys are preserved below the level of the Central Court. Today, a large part of it has been reconstructed in concrete.
The storeys are connected with one another by means of a system of stairs known as the "Grand Staircase". The staircase was found during the excavation in its original position. There is a total of four flights of stairs, two for each storey. The two lower flights are preserved as they were found. The steps are broad and deep, with a gentle incline that makes for an easy ascent. The staircase is lit by a large light-well and was surrounded by a colonnade of wooden columns.The Grand StaircaseThe Grand StaircaseThe Grand Staircase & Hall of Colonades - First floorThe Grand Staircase & Hall of Colonades - Ground floor
A series of corridors, spacious halls and small rooms is connected to the Grand Staircase. Evans, who believed that the Palace was the seat of the king of Knossos, hypnothesized that the residential quarters of the Royal family lay in this part of the site.
