Wilson's Arch and Jerusalem's Great Causeway

Nineteenth-century surveyors documented the arch, while modern Israel Antiquities Authority excavations opened sealed spaces and stratified deposits beneath it. Recent work has refined the sequence rather than treating every visible stone as one Herodian event. Modern investigation matters because the evidentiary claim depends on recorded provenience, architectural joins, sealed deposits, and publication—not merely on a monument being visible today. Earlier reports and later reassessments are read together so that restoration, reconstruction, and newly refined phasing are not mistaken for untouched ancient context.

A great stone arch springs from the western retaining wall and formed part of a series of vaults supporting an elevated crossing. Adjacent rooms, channels, and street levels show how access, drainage, and urban growth were coordinated at the foot of the Temple Mount. Architectural evidence is cumulative: wall bonds, thresholds, floor levels, installations, reused blocks, associated ceramics, inscriptions, and traces of destruction or repair work together. The dossier therefore describes the whole controlled assemblage and avoids assigning a biblical label to an isolated feature solely because it looks familiar.

Some components belong to the late Second Temple building program, while other phases continued or changed after AD 70. Dating depends on construction relationships, coins, pottery, radiocarbon work, and the distinction between the arch and the causeway system. Dates in the dossier are archaeological ranges, not precision timestamps. They depend on stratigraphy, ceramic typology, coins, inscriptions, radiocarbon evidence where available, and comparison with regional sequences. A biblical passage can supply historical context, but it does not override the excavated sequence.
