Madaba is best known for its collection of Byzantine-era mosaics. The most famous of them, the remains of a 6th-Century floor mosaic housed in the modest St George Orthodox church, is considered the oldest surviving map of the Holy Land, and depicts various sites linked by the King"s Highway. Near the church"s altar, I tried to decipher the Greek captions indicating Jerusalem in the centre of the map, and marvelled at the details of fish swimming in the River Jordan and boats on the Dead Sea.
