Al Qastal (Qastal Palace)

Al Qastal is considered to have once been a roman fort, because of its shape and the assumption that its Arabic name Qastal derived from the Latin word 'Castellum' or small castle.

To the north of the qasr is a mosque with a round tower resting on a square base.

This tower, with its spiral staircase, is all that remains of a minaret, which may be the earliest surviving minaret in the Islamic world.
