Jordan, Madaba, May 2009
The Madaba Mosaic Map is an index map of Palestina, dating from the sixth century CE, preserved in the floor of the Greek Orthodox Basilica of Saint George. With two million pieces of colored stone, the map depicts hills and valleys, villages and towns in Palestine and the Nile Delta. The mosaic contains the earliest extant representation of Byzantine Jerusalem, labeled the "Holy City." The map provides important details as to its 6th century landmarks, with the cardo, or central colonnaded street and the Holy Sepulchre clearly visible:
