What Israel Just Found Buried Deep Under Jerusalem | Grand Structures

For centuries, pilgrims visiting Jerusalem were shown the Pool of Siloam—the famous site mentioned in the Gospel of John. But for roughly a hundred years, serious scholars doubted its authenticity, believing it was either symbolic or built centuries too late to match the biblical account. Then, in the autumn of 2004, a repair crew fixing a broken sewer line hit something beneath the soil that changed everything. In this documentary, we break down the archaeological evidence surrounding the true Pool of Siloam and the massive engineering systems beneath Jerusalem. Discover how radiocarbon dating and stalactite growth proved the age of the 1,750-foot Hezekiah's Tunnel, how 100 small coins sealed beneath the Pilgrimage Road challenged long-held assumptions about its construction, and what the physical record actually proves—and doesn't prove—about the site's final days during the Roman siege of 70 CE.
