The foundations of this Byzantine church in Mazraat Kfarzebian were discovered in the early 60s during excavation works. It looks like it's laying against the northern wall of Atargatis Temple.
Experts think the church was built in the 5th or 6th century: Christianity became the State religion in the Byzantine State at the beginning of the 5th century. The destruction of pagan temples was then allowed, and those temples were sometimes turned into churches.
The temple of Atargatis was too small for its new religious functions. This is probably why the Byzantine church was annexed. It was built on a rectangular plan and it measures about 23.5 m by 12.5 m. The outside walls of the church are mainly made of limestone blocks.
