The west wing was devoted to religious activity. The main entrance was opposite the altar in the court, and was flanked by two other smaller ones. The building had an antechamber, a chamber and a large "ceremonial" hypostyle hall (12 x 10 m.) with a peristyle light-well and polythyra (pier-and-door partitions), one of which gave access to a "banquet hall", thus called because it contained amphoras and jugs. The west part of the wing is occupied by the shrine which consists of 11 rooms, some of which had niches. The main part of the shrine was a small room - not accessible to the public - with a high bench for the deposition of cult objects. Beside it there was a subterranean lustral basin, while to the south there were three auxiliary rooms: a stone cutter's workshop, a storeroom, and the treasury - the only Minoan treasury which was found unrobbed and yielded a series of superb ritual vessels.
