It was built in either the second quarter: 53 or the second half of the second century AD,: 143 and is constructed of black basalt.: 141 It is likely that the theatre was built during the reign of Trajan.
The theatre was originally built outside the walls of the town, but was later completely enclosed by an Ayyūbid fortress.: 141 The city of Bosra had its fortifications expanded between 481 and 1251. When later integrated into the fortifications, its role was to serve as a citadel and to guard a road leading to Damascus.
The theatre is 102 metres across and has seating for about 17,000 people; it is thus among the largest of the Ancient Roman civilisation.: 141 It served a city that once had 80,000 inhabitants. It is also one of the best preserved both in Syria and across the Roman empire. It was substantially restored between 1947 and 1970, before which it contained large quantities of sand, which may have helped to protect the interior.: 141
