The Madaba mosaic map is one of the oldest surviving maps of Jerusalem.
“A famous Byzantine mosaic map, discovered in 1896 in the town of Madaba in Jordan. The mosaic, dated to the sixth century, emphasizes Christian sites throughout the biblical lands. The map bears the names of the sites in Greek. In the center of the map, greatly enlarged, is a map of Christian Jerusalem”
Cartographers have superimposed an image of the Madaba map onto a modern map of the old city of Jerusalem and found that the mosaic was remarkably accurate
