The Western Wall — the Kotel — is the most visible surviving fragment of the Second Temple complex. Mainstream archaeology places it as the western retaining wall of Herod the Great's expanded Temple Mount platform, raised in the decades before AD 30. The lower courses display the characteristic Herodian ashlar: massive limestone blocks with marginal drafting and a recessed central boss, the same masonry pattern preserved at Wilson's Arch, Robinson's Arch, and the Hulda Gates along the southern wall. Josephus, in Antiquities 15.392-402 and Jewish War 5.184-227, describes Herod's expansion as a platform raised by enormous walls supporting the sacred precinct above. The Trumpeting Place inscription, recovered in 1968 at the foot of the southwestern corner and now in the Israel Museum, reads LBYT HTQYAH — "to the place of trumpeting" — fixing the priestly station at the platform's edge and confirming the structure as the Temple Mount, not a Roman garrison. A minority hypothesis — advanced by Ernest L. Martin in The Temples That Jerusalem Forgot (2000) and Bob Cornuke in Temple (2014) — argues that the present Temple Mount platform was the Antonia Fortress, a Roman military stronghold, and that the genuine Temple stood further south near the Gihon Spring in the City of David. The relocation theory is rejected by the working consensus of Jerusalem archaeologists, including Dan Bahat, Leen Ritmeyer, and Eilat Mazar. The Herodian platform's dimensions — roughly 488 by 305 meters — vastly exceed any known Roman fort. Mikvaot, the ritual baths used by priests before entering the sanctuary, line the southern approach in numbers no garrison would require. Josephus's geography of the Temple precinct, the trajectory of Robinson's Arch, and the alignment of the Hulda Gates all converge on the present site. Josephus records the destruction directly. In Jewish War 6.249-281 he narrates the burning of the Temple itself on Av 9-10, AD 70, the fire consuming the sanctuary and its courts. Wars 7.1 reports that Caesar then ordered the demolition of the entire city and temple, sparing only the three towers — Phasaelus, Hippicus, Mariamne — and the western city wall as a perimeter for the Roman garrison. The Temple proper, the Naos and its surrounding buildings, was leveled. The retaining walls of the platform — the substructure that supported the Temple, not the Temple itself — were left standing. This distinction is the key to reading Matthew 24:2 in context. Jesus, departing the Temple complex (τοῦ ἱεροῦ), responds to the disciples' admiration of the buildings (οἰκοδομάς) with the prophecy that "not one stone shall be left here upon another, that shall not be thrown down." The standard exegesis — represented by D.A. Carson and the Davies-Allison ICC commentary — reads ἱερόν here as the Temple buildings on the platform, not the retaining walls beneath. The Western Wall's survival does not falsify the prophecy. Christ spoke of the buildings; the buildings fell. The Olivet Discourse continues into the eschatological signs of verses 15-31, which the post-tribulational reading places at Christ's single return after the tribulation — one coming, after the church passes through the great distress. The Western Wall stands today as the most enduring physical witness to the precision of Christ's prediction. The Temple was destroyed exactly as foretold. The platform that carried it, by Roman administrative decision, remained.
