Part of the Old City's Jewish Quarter, the Cardo is the reconstructed
main street of Byzantine Jerusalem from the 6th century. This street,
with columns along its entire length, used to be a long avenue that
crossed the whole city from north to south. Today, situated 20 feet
below modern street level, one part of the Cardo is a restored arcade
of Jewish galleries and shops, while the other part is an open-air
reconstructed street.
At one point along the roofed arcade you can look down to a level
surface underneath the street and see remnants from the time of the
First and Second Temple (10th and 1st centuries BC).
