Unprecedented Excavations Between the Pool of Siloam and the Temple Mount

The Pool of Siloam: Where Archaeology Met the Gospel

In 2004, during routine repair work on a sewer line in the southern part of the City of David in Jerusalem, construction workers accidentally uncovered a set of ancient stone steps. What followed would become one of the most significant archaeological discoveries of the 21st century: the Pool of Siloam, a site directly mentioned in the Gospel of John, chapter 9, where Jesus healed a man born blind.

The biblical account records that Jesus made mud with saliva, anointed the blind man's eyes, and told him: "Go, wash in the Pool of Siloam." The man obeyed, washed himself, and returned seeing. The excavation of the actual Pool of Siloam demonstrates that the Gospel writer possessed accurate topographical knowledge of Jerusalem.

The excavations, led by archaeologists Ronny Reich and Eli Shukron of the Israel Antiquities Authority, revealed a monumental stepped pool measuring approximately 50 meters in length. The pool was fed by the waters of the Gihon Spring through Hezekiah's Tunnel. Coins found embedded in the plaster date its construction to the late Hasmonean period (around 100 BC).

Between 2019 and 2024, a new phase of excavations fully exposed the pool for the first time in nearly two millennia. The results exceeded expectations: finely cut limestone steps in a remarkable state of preservation, drainage channels, surrounding pavement stones, oil lamps, stone vessels typical of Jewish purity practices, and fragments of pilgrim flasks.

The Pilgrimage Road: Jerusalem's Sacred Way

The Pool of Siloam served as the starting point of a grand stone-paved road that climbed northward through ancient Jerusalem to the Temple Mount. Known as the Pilgrimage Road (Derech Ha'Olim), this thoroughfare stretched approximately 600 meters in length and 8 meters in width.

Excavations began in 2013 under Nahshon Szanton and Joe Uziel of the IAA. The road was found buried under destruction debris from the Roman siege of AD 70. Based on coins found beneath the paving stones, the road was built during the administration of Pontius Pilate — meaning Jesus would have walked on these very stones.

Material Finds: Pottery, Coins, and Inscriptions

Thousands of coins have been recovered, including bronze prutot bearing the name of Pontius Pilate dated to AD 29/30. Stone vessels — which according to Jewish law cannot become ritually impure — confirm strict observance of purity laws (cf. John 2:6). Dozens of oil lamps, inscribed fragments, architectural elements, and organic remains including charred date pits and olive stones were also found.

The Ritual Route: From Pool to Temple

The pilgrim would first purify in the Pool of Siloam, then ascend the Pilgrimage Road, passing shops where offerings could be purchased. The Psalms of Ascent (Psalms 120-134) would have echoed along the road. At the top, pilgrims reached the monumental staircase at the southwestern corner of the Temple Mount near Robinson's Arch, entering through the Hulda Gates.

Modern Technologies in the Excavations

The project uses LiDAR scanning for 3D models, Ground-Penetrating Radar to identify buried structures, photogrammetry for digital preservation, micro-archaeology and wet sieving to recover tiny artifacts, radiocarbon dating, and digital infrastructure monitoring to protect modern buildings above the excavations.

The 2025 Inauguration: Stones That Speak

In 2025, the fully excavated Pool of Siloam was opened to the public for the first time in nearly two thousand years. Visitors descended the ancient stone steps and walked along the Pilgrimage Road. As one leading archaeologist commented: "These stones speak. They tell the story of a city, a people, and a faith that shaped the course of human history."

Theological and Historical Implications

The discoveries confirm Gospel topography, demonstrate the historical reliability of John's Gospel (Pool of Siloam, Pool of Bethesda, Stone Pavement/Gabbatha), illuminate Jewish ritual life of the Second Temple period, illustrate the destruction of AD 70 fulfilling Jesus' prophecy (Mark 13:2), and raise questions about cultural memory and continuity.

What Still Lies Ahead

Significant sections of the Pilgrimage Road remain unexcavated. The drainage channel beneath the road — where Jewish refugees hid during the Roman siege — has been only partially explored. Advanced scientific analysis including ancient DNA studies and isotopic analysis will reveal more about the population and trade networks of ancient Jerusalem.

Conclusion

The excavations between the Pool of Siloam and the Temple Mount represent one of the most important archaeological projects in biblical research. The Pool of Siloam is now a documented archaeological site, its stone steps restored after two millennia. The Pilgrimage Road has been uncovered stone by stone, connecting text and ground, faith and evidence, the ancient world and the modern.
