According to Cyril of Scythopolis, the church was built in 456 CE, by a widow named Ikelia. Three phases have been identified in the church. In each phase a new mosaic floor was laid above the previous one. No major architectonic changes occurred to the general octagonal plan of the church. The phases were dated mainly by coins. Phase I is dated to mid 5th century CE.

In Phase II the bema was extended to the west, into the ambulatory, by adding of two parallel walls with two staircases between them that led to the bema. The pillars and columns separating between the internal octagon and the ambulatory were replaced by narrower ones, a change that can point to an alternations on the roofing of the central octagon. To this phase also belongs a ceramic pipe that led water from an unknown source to a socket in the central rock.
