Archaeological remains

General description

State of preservation/which parts were uncovered: 
Circular church with entrance from the south. Only five buttresses of the Byzantine church were uncovered.

Description

Illustrative material: 
Façade and entries: 

The reconstructed diameter of the church was 36.7 m. The entrance to the church was from the south.

External Walls (for a concentric church): 

The middle wall was surrounded by an outer wall that presumably runs on the rout of the Crusader, octagonal wall.

Central space: 

The Byzantine church was circular, probably with no apsis. Its inner part was covered by a dome opened in its center. The dome was based on a circle of columns. The rock under the dome was surrounded by bronze trellis. The altar was placed to the east of the trellis, under the dome.

Ambulatory: 

The inner part was surrounded by a circular corridor that in turn, was surrounded by a middle wall. The diameter of this wall was 26.5 m. This wall (1.4 m thick) was supported by buttresses. Five buttresses have been uncovered and cleaned. Each one is approximately 3.7 m. long. At their ends the width is twice what it is abutting the wall. The buttresses are at a height of 8 m. above the rock.

Architectural Evolution

General outlineDating materialPhase no.CenturyWithin century
The Byzantine church was circular, probably with no apsis. Its inner part was covered by a dome.

According to the literary sources it was constructed by a righteous woman named Poemenia, a relation of emperor Theodosius I at the second half of the fourth century (before 378 CE according to John Rufus, Life of Peter the Iberian 43, 59ff in Horn and Phenix translation). Other sources attribute it to Constantine. 

Phase 1
4th c.
Second half
The church was damaged by the Persians in 614 CE and restored by patriarch Modestus (died between 630 and 634), after Byzantine regime was restored (PG 89, 1427). This is also indicated in a inscription (see the Epigraphy section). Arculf, in 670, described it as a circular church (rotunda), surrounded by two rows of columns. The church is mentioned in the Commemoratorium (808 CE).
Phase 2
7th c.
Early
Its fate later in the Early Muslim period is unknown. The Crusaders church that replaced it was octagonal. Its floor elevation was higher than that of the circular church.
