The synagogue was built on the southern slope of the hill, on a terrace cut into the slope, with the façade facing east.
Phase I (Large synagogue, 3rd century CE) The synagogue's first phase is dated to the 3rd century CE in the Late Roman period, based on coinage, pottery, and its characteristic architectural style. It remained in use until it was apparently destroyed deliberately in the 4th or early 5th century CE, possibly in the context of Byzantine persecution of Jews or as a result of the wider impact of the Samaritan revolts reaching the Carmel region. The building likely had the plan of a
basilica, estimated to measure 14.80 x 23.80 m including the narthex. The excavators, Dar and Mintzker, write that "the walls were constructed of large
ashlar stones, shaped by combed-chisel dressing and assembled with fine joints without
mortar." To achieve a level floor, builders "cut into the bedrock on the building's northern side and built the up foundations on the southern side." The eastern façade show evidence of three doors. Fragments, including a frieze suggesting the angle of the gable, several cornices, and a conch decoration for a window lintel, help reconstruct the façade's original look. Fragments of a three-dimensional eagle statue were found and may have belonged to an art piece that once stood above the main doorway. A massive lintel fragment decorated with a lion and a goblet was also uncovered outside the façade. In the 19th century this lintel was still complete, showing two lions facing a goblet between them, with a small cup above one of the lions, as recorded by the PEF survey team. A stone fragment bearing part of a recessed frame and the
Hebrew letter mem or
lamed was also discovered, reused in a step dating to the medieval period. Two sets of stylistically identical Ionic columns were present: larger ones were seemingly used for the main room and smaller ones for the narthex. A hard lime plastered floor was found, constructed in three layers: stone soling, rammed lime with crushed stones, and a hard lime plaster finish.
Phase II (Smaller rebuilt synagogue, 5th–7th centuries CE) The structure underwent major changes in the late Byzantine period. Internal walls narrowed the original hall to approximately 10 x 15 m. Benches were added along the plastered walls. Five grooved pillars were found upright within the synagogue; they had different diameters and heights and were likely brought from the nearby industrial workshops to repair the building, as they were not part of the original construction. A small menorah scratched on the façade wall suggests the building may have continued to function as a Jewish place of worship during this phase. A small hoard of six Byzantine coins was discovered, the latest dating to 618/619 CE, during the reign of
Heraclius, the last Byzantine emperor to rule the Levant before the Muslim conquest.
Phase III (Domestic use, 11th–15th centuries CE) After abandonment, likely in the early Islamic period, the synagogue was reused in the Middle Ages, but not as a synagogue: instead, the remains of kitchenware, animal bones and ovens, found in the eastern wall, points to domestic use.
Assessment and identification The interpretation of the structure has been questioned by some scholars. Adam L. Porter, a scholar of religion, noted that the building exhibits several architectural features atypical of ancient synagogues, including an east–west orientation rather than facing Jerusalem and the absence of elements commonly associated with synagogues, such as a
bema,
Torah niche, or fixed benches along the walls. Yehudit Turnheim, a scholar of ancient art, similarly argued that these features complicate the identification of the building as a synagogue. At the same time, Turnheim cautions that ancient synagogues exhibit significant regional variation and concludes that each structure must be evaluated on its own merits. == Structures and installations ==
