Al Qastal (Arabic: القسطل) is a town in the Amman Governorate of northern Jordan.
Textual evidence from the poet Kuthayyir 'Azzah indicates that the Qasr al-Qastal complex was originally built by Caliph Yazid bin Abd al-Malik.
[dubious – discuss] When the Abbasid Caliphate fell, there was a short period when the site was abandoned.
Later, under the Ayyubid and Mamluk dynasties, Al-Qastal was re-settled, a number of small buildings dating back to this time.
The upper story contained another set of suites and the palace's audience hall which had a triple, apse design.
