9532: Bull Bastion on the west side of the Palace of Knossos. An open air passage linked the Central Court with the North Entrance. It was paved and sharply inclined towards the north. The passage is narrow. Right and left were two raised colonnades known as "Bastions". Arthur Evans reconstructed the "Bastion" on the west side. He also placed a copy of a restored relief fresco of a bull here. The wall painting may have formed part of a hunting scene. The passage ends in a large hall with ten square pillars and two columns. The pillars and columns probably supported a large hall on the upper floor. Evans suggested that, due to its position on the seaward side, it was here that the produce of seaborne trade would have been checked when it reached the Palace. It was therefore named the "Customs House".
