Umm Er Rasas is a city located on the King’s road, between Madaba and Karak. We date this city from the Nabatean, Roman, and especially Byzantine periods. Inside the surrounding walls of the city you find a fantastic puzzle in disorder of reversed towers, and churches into pieces. Despite this first impression we had found one of the most beautiful mosaics in Jordan. A mosaic representing the principal cities on both banks of the rift, which divides the Holy Land in two.
