Amman Citadel is an archaeological site located on a hill in the city of Amman, the capital of Jordan. The earliest evidence of settlement in the region dates back to the Neolithic period, while the fortification of the hill dates back to the Bronze Age around 1800 BC. In the first millennium BC the hill became the capital of the Kingdom of Ammon. After that, many civilizations occupied the city: the Assyrians, Babylonians, Ptolemies, Seleucids, Romans and Byzantines until the Umayyads came in the 7th century AD. The hill has a large collection of monuments that testify to the historical eras it passed through, including the Temple of Hercules, the Roman Theater, the Byzantine Church, the Umayyad Palace and the Ayyubid Tower.
