Bosra Citadel is considered one of the most significant fortresses in the Middle East. Originally constructed as a Roman amphitheater in the 2nd century AD, it was later transformed into a fortified castle during the Islamic periods, particularly under the Ayyubid dynasty. Strategically located along the route of the Syrian Hajj caravan, the citadel served as a vital military and logistical station, blending monumental Roman architecture with successive layers of Islamic defensive adaptations.
