The Threshold of the City
Recognizing the quarry is easy once you know what to look for. Proving it was outside the city walls in the first century is more challenging.
The need for the CHS to be "outside" is driven by the presence of first-century graves found in the lower portions of the quarry. Because Jewish custom considered tombs ritually unclean, it is inconceivable that executions would be conducted or the dead buried inside the city limits. This aligns with Hebrews 13:12, which states that Jesus “suffered outside the gate.”
The confusion for the modern visitor comes from the fact that the Old City walls we see today encompass the CHS. While this line corresponds in places to earlier boundaries, these walls were raised by the Ottomans, some 15 centuries after the biblical period. They are irrelevant to the discussion.
The Jewish historian Josephus describes three different first-century wall systems. For our purposes, his Second Wall is the key. Its exact path has been debated for a century or more. Josephus’s clues are few: it started at the Gennath (Garden) Gate, encompassed a part of the northern city, and terminated at the Antonia Fortress. While archaeological evidence for the Second Wall remains enigmatic, the best recent data comes from a 2020 radar survey near the Lutheran Church of the Redeemer. Faint readings suggest the crowning of a wall, supporting the consensus that the Second Wall "zig-zagged" leaving this quarry—a place of rejection and discarded stone—just outside the gate.
