Qasr Amra, situated 75km East of Amman on highway 40, is one of the best-preserved monuments and is a UNESCO World Heritage Site. Its interior walls and ceilings are covered with lively frescoes, and two of the rooms are paved with colourful mosaics. The paintings include themes such as hunting, dancing, and musicians, bathing scenes, cupids, and personifications of history, philosophy and poetry. Most of the buildings are still standing and can be visited. The plan of the building consists of 3 main elements: a rectangular audience hall with a throne alcove in the middle of the south side, a bath complex which comprises 3 rooms corresponding to the frigidarium, tepidarium and calidarium, i.e. the cold, warm and hot rooms respectively and the hydraulic structures which include an elevated water-tank, a masonry-lined deep well, and the apparatus for drawing water from the well into the water tank. Two feeder pipes drained water from the elevated tank to the shallow pool or fountain in the audience hall into a plastered tank, which stood above the furnace. Recent excavations by the Spanish Archaeological Mission discovered the foundations of a smaller courtyard castle.
