During Byzantine Jerusalem a sunken north-south thoroughfare was built across the city, from what is now the Damascus Gate southward toward the Zion Gate. The general term for such a main street in Ancient Roman cities was cardo maximus, and today, the street is simply called The Cardo.
Today the Cardo begins just south of David St. and is only half its original width — it was once as wide as a six-lane highway — and passes into the modern-day Jewish Quarter. A walk along the Cardo will reveal a strip of high-end shops selling souvenirs, Judaica, jewelry and artwork. A southern portion of the Cardo has been restored with colonnaded walkways, much like it had during the sixth century.
The area surrounding the Cardo contains several worthwhile archaeological excavations of the First and Second Temples.
