Double reservoir healing pool with five colonnades excavated north of the Temple Mount at St. Anne's
A large double-basin reservoir divided by a central rock dyke, providing exactly five porticoes or colonnades (four surrounding the perimeter and one dividing the two pools), matching the architectural layout in John 5.
Rigorous 4-part empirical analysis separating ancient text from bias and consensus
Archaeological excavations revealed a northern pool (for water storage) and a southern pool with stone steps for bathing, surrounded by four porticoes and divided by a fifth central colonnade, overlaid with Roman healing baths (Asclepieion).
19th-century commentators treated the 'five porticoes' as allegorical (representing the five books of Moses); Conrad Schick and the White Fathers' excavations proved it was an exact physical architectural reality.
Second Temple municipal water reservoir and healing sanctuary; later converted under Hadrian into a Greco-Roman medicinal Asclepius shrine.
