Ancient City of Bosra: Black Basalt Theatre and Old Caravan Trails
How Roman builders used black volcanic rock to build a grand theatre inside a medieval fortress in southern Syria.
Nabataean Caravan Crossroads, Trajan Capital, and Black Basalt
Bosra is an ancient stone city standing in the green Hauran plain of southern Syria. Long ago, wealthy Nabataean traders rested their camel caravans in this busy desert oasis. In one hundred and six, Roman Emperor Trajan made Bosra the capital of the Arabian province. Masons cut hard black volcanic basalt stone from nearby fields to build grand city arches. UNESCO named the Ancient City of Bosra a World Heritage site in 1980. A long straight Roman road paved with dark basalt stones crossed through the city center.
The Black Basalt Roman Theatre and Ayyubid Citadel
Roman builders completed a giant black basalt theatre during the second century. The wide round theatre held fifteen thousand cheering spectators across steep stone benches. The tall stage building featured two rows of fine white columns and beautiful carved stone. Centuries later, Ayyubid Muslim rulers built a thick fortress with nine towers around the theatre. Soldiers dug a deep dry ditch around the high fortress walls to keep enemy armies away. These strong fortress walls protected the old Roman seats and stage from breaking apart.
