Is the capital city of Madaba Governorate in central Jordan, with a population of about 60,000. It is best known for its Byzantine and Umayyad mosaics, especially a large Byzantine-era mosaic map of the Holy Land. Madaba is located 30 kilometres (19 miles) south-west of the capital Amman. Madaba dates from the Middle Bronze Age. The town of Madaba was once a Moabite border city, mentioned in the Bible, Control over the city changed back and forth between Israel and Moab, as mentioned in the Mesha Stele. The first evidence for a Christian community in the city, with its own bishop, is found in the Acts of the Council of Chalcedon in 451, where Constantine, Metropolitan Archbishop of Bostra (the provincial capital) signed on behalf of Gaiano, "Bishop of the Medabeni." During the rule of the Islamic Umayyad Caliphate, it was part of the southern district of Jund Filastin within the Bilad al-Sham province. The first mosaics were discovered during the building of new houses using bricks from older buildings. The new inhabitants of Madaba, made conscious of the importance of the mosaics by their priests, made sure that they took care of and preserved all the mosaics that came to light. A 6th-century mosaic map of Jerusalem in the Madaba Map The Map of Madaba mosaic was discovered in 1896 and the findings were published a year later. This discovery drew the attention of scholars worldwide. It also positively influenced the inhabitants, who shared the contagious passion of F. Giuseppe Manfredi, to whom the rediscovery of most of the city's mosaics are owed. Madaba became known as the "City of Mosaics" in Jordan. The Madaba Mosaic Map is a map of the region dating from the 6th century and preserved in the floor of the Greek Orthodox Basilica of Saint George, sometimes called the "Church of the Map". With two million pieces of coloured 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 about its 6th-century landmarks, with the cardo, or central colonnaded street, and the church of the Holy Sepulchre clearly visible. This map is one key in developing scholarly knowledge about the physical layout of Jerusalem after its destruction and rebuilding in 70 AD. Other mosaic masterpieces found in the Church of the Virgin and the Apostles and the Archaeological Museum, depict a profusion of flowers and plants, birds and fish, animals and exotic beasts, as well as scenes from mythology and everyday pursuits of hunting, fishing and farming. Hundreds of other mosaics from the 5th through the 7th centuries are scattered throughout Madaba.
