On the southern side of the hypostyle, a door opened onto a large reception room ornamented with decorations including wooden sconces, painted protomes of lions, and geometrical art; this room was probably enclosed, as it had no drainage system, and allowed access to the other areas of the palace through doors on every side. The palace was divided into three zones, each serving different functions, and linked by a network of courtyards and long corridors, which were carefully placed, allowing both seclusion and easy access for royalty and highly ranked officials. South of the reception area lay a suite of rooms that would have served as the administrative quarters, consisting of a quadrangular block of two pairs of units separated from each other by corridors meeting at right angles; the eastern pair were used as audience halls, while the western pair possibly functioned as chancelleries. The entrances to the chambers from the encircling corridors were offset, meaning that, in theory, two separate groups could have entered the complex, been allowed an audience, received a decision, and left, without seeing each other. West of the administrative quarter, on the southwestern side of the palace, lay two units that were identified, by the presence of bathrooms, as residential in purpose. In layout, the structures were similar to other residences excavated in the city, with a small courtyard to the north and living quarters to the south. The larger of the units, which contained other features such as a small iwan behind the courtyard, lay to the west and was separated from its smaller neighbour by an isolating corridor. The three-room bathrooms lay to the rear of the units and were tiled with limestone slabs and pebble mosaics of palmettes and marine animals, continuing an existing tradition of Hellenistic art. Based on the more private nature of the western unit, scholars have speculated that it was intended for the sovereign's family, as contrasted with the eastern unit, which was probably intended for the monarch himself and his intimate companions. North of the residential units lay a small courtyard, which was connected to a small library in the treasury. Treasury The treasury building, on the western side of the palace courtyard, from which it could be entered, constituted the third zone. This building was of late construction, as the treasury itself was likely previously located in buildings east of the courtyard. In its latest
