Bosra is an ancient city administratively belonging to the Daraa Governorate in southern Syria. It is a major archaeological site and has been declared a UNESCO World Heritage Site. The settlement was first mentioned in the documents of Tutmose III and Akhenaton (14th century BC). Bosra was the first Nabatean city in the 2nd century BC. The Nabatean Kingdom was conquered by Cornelius Palma, a general of Trajan, in 106. Under the Roman Empire, Bosra was renamed Nova Trajana Bostra, and was the residence of the legio III Cyrenaica and capital of the Roman province Arabia Petraea. Bosra played an important part in the early life of the Prophet of Islam, Mohammed as described in the entry for the Christian Monk, Bahira. Bahira was witnessing to Muhammad in the prophethood. Today, Bosra is a major archaeological site, containing ruins from Roman, Byzantine, and Muslim times, its main feature being the well preserved Roman theatre. Every year there is a national music festival hosted in the main theater.
