Dentzer et al. (2002:91) documented major architectural modifications to the large centrally planned church at Bosra (also referred to as the cathedral, central church, or large church), originally constructed in the late 5th century CE. Ceramic evidence dated these alterations to the end of the 6th century CE, and the authors suggest that the reconstruction was likely triggered by seismic damage from a mid-6th century earthquake, potentially the 551 CE Beirut Quake. Dentzer et al. (2002:91 n. 49) further observed that such an earthquake might explain the cracks in the ground embankment observed near the south-eastern exedra. Dentzer et al. (2002:92) further speculated that the large pipe crossing the central church may have been constructed during the late 6th century CE modifications.
