Cardo main street - Medeba Map
A 6th c. church floor in Medeba in Jordan, has a mosaic map of the land of Israel with numerous place names in Greek. The center of the map is an open-faced depiction of Jerusalem with the city walls, gates, churches (with red roofs), and the Cardo. This main street of the city is depicted with two rows of colonnades running the length of the city from north to south.
The central street of the Cardo is 12 meters wide and is lined on both sides with columns. The total width of the street and shopping areas on either side is 22 meters, the equivalent of a 4-lane highway today. This street was the main thoroughfare of Byzantine Jerusalem and served both residents and pilgrims. Large churches flanked the Cardo in several places.
