About Umm ar-Rasas (Kastron Mefaa)
Desert frontier city on Via Nova Traiana, Umm ar-Rasas contains Roman castrum, five Byzantine churches with superb mosaic floors, and the intact 14×6 m mosaic map in St Stephen's Church (718 CE) – the largest Jordan mosaic and second complete Palestinian city map after Madaba. Includes Simeon Stylites tower complex, reservoirs, and Umayyad period occupation. Remote steppe setting preserves unexcavated tell and extensive agricultural hinterland.
