Some of us shopped in the Cardo (the ‘heart’ of the walled city), and some of us visited the Southern Wall excavations that have recently been unearthed. It was at this location that pilgrims coming to Jerusalem would stop to purchase animals for sacrifice or to exchange money to make their payments of the half-shekel head tax that was paid each year. In the Davidson Archeological Center they showed us an interactive 3-D simulation of the Old City history.
