The Greek Orthodox Church of St. George is known as the "Church of the Map". It is one of the most beautiful churches in the world and is one of the main places of worship and pilgrimage throughout Jordan. Decorated with opulent interiors, elegant columns and various mosaics, the Greek Orthodox Church of St. George hosts the mosaic map of the Holy Land. The Madaba Map was discovered in 1896, a map of the Middle East dating back to the sixth century and preserved in the floor of the Greek Orthodox Church of St. George's Church, which is why it is called the "Church of the Map". With two million pieces of colored stone, the map depicts hills, valleys, villages and towns in Palestine and the Nile Delta and dates back to the sixth century, and is part of the Madaba Mosaic Map, which contains the oldest pictorial representation of the land of Jerusalem.
