Jordan
Well over three hundred sites, including over 150 well-preserved churches, provide abundant archaeological information on Christianity in Jordan. Archaeological investigation over the past hundred years has often focused on revealing architecture and mosaic floors, while careful, improved excavation techniques and use of scientific methods of analysis of finds in recent decades provide insights into anthropological topics, such as occupational history; standards of post-excavation conservation have improved as well. From their origins in the fourth century, material forms of Christianity spread in the fifth century and reached their high point in the sixth and seventh centuries, continuing into the early Islamic period, only to decline in the eighth century and beyond.
