From the Main Theater to the Qasa Al-Bint (background) is the Colonnaded Street. The ancient shops once flanking this avenue are gone or are in ruins. However, you will find a modern archaeological museum and a restaurant along this pedestrian walkway. The Cardo Maximus was built by the Romans after they took control of Petra in 106 AD. That year marked the end of the Nabataean Era. The city then became part of the Roman Empire’s Provincia Arabia.
