The palace, bath complex, and external mosque are enclosed by a retaining wall. The southern gate was known from Baramki's excavations, but the 21st-century discovery of a northern gate in alignment indicates that the development of Hisham's Palace was conceived of as a complete unit to be constructed at once.
Palace The largest building at the site is the palace, a roughly square building with round towers at the corners. It originally had two stories. Entrance was through a gate on the center of the east side. The inner rooms were aligned around a central paved portico (
riwaq), which featured an underground cellar (
sirdab); for refuge from the heat. The room to the south of the portico was a mosque with a
mihrab built into the outer wall.
Bath complex The bath complex is located just north of the palace across an open area. This free-standing structure is almost 30 meters square, more precisely , and three of its sides feature semi-circular
exedrae which project out from the building, three each to the south and west, and two to the east. The east face of the bath had an ornate entrance in its center, flanked by exedrae. Along much of the southern side of the main, square hall is a pool. The interior floor surface of the bath complex was paved with mosaic decoration. A special reception room, or
diwan, was entered from the northwest corner. The floor of this room is paved with the famous "
tree of life" mosaic, depicting a lion and gazelles at the foot of a tree. The actual bathing rooms were attached to the northern wall of the complex, and were heated from below the floor by
hypocausts.
Agricultural annex To the north of the bath complex are the ruins of a large square structure which has clearly gone through many phases of reuse and reconstruction. This part of the site was initially assumed to be a
khan or
caravanserai, but recent excavations have indicated that the northern area had an agricultural function connected to the
hayr or agricultural enclosure during the Umayyad and
Abbasid periods.
