Umm Hadder

Umm Hadder is a small Hellenistic fortress located along the Wadi al-Kufrayn, just north of the Kufrayn dam in Jordan. The fortress is approximately 40 by 30 meters in size and consists of rows of rooms around a central courtyard, with towers in each of its corners. A large well is located in the middle of the open courtyard.

Umm Hadder is one of several fortresses and many settlements along the Wadi al-Kufrayn during the Iron through the Hellenistic periods. The Wadi al-Kufrayn was probably one of the main access routes from the Jordan valley to the Ammonite plain.
