It was the Roman capital for the Arabic region and located in the middle of a fertile valley. There is a big gate leading to the city with its old paved roads. The lively and brilliant colors of costumes in this city create a strange, charming and amazing contrast with the dark and gloomy color of the basaltic stones of the temples, palaces, high columns and mosques dating back to middle ages. In Bosra, there is a magnificent amphitheater dating back to the second century AD and can accommodate up to 15000 audiences.
