An Israel Antiquities Authority team has reexcavated an area of the Hasmonean city wall dating from the 3rd century BCE. The area excavated is on the south side of Mt. Zion next to the Catholic Cemetery where Oskar Schindler is buried. The wall (including a tower preserved to 3m in height) was originally excavated by Bliss and Dickie in the late 1800’s using a tunneling system. Not exactly the best way to do archaeology. Remains of the Byzantine city wall were also discovered.
