Wadi Ara (Arabic: وادي عارة; Hebrew: ואדי עארה) or Nahal 'Iron (Hebrew: נחל עירון), is a valley and its surrounding area in Israel populated mainly by Arab Israelis. The area is also known as the "Northern Triangle".
Wadi Ara is located northwest of the Green Line, in the Haifa District. Highway 65 runs through the wadi. The ancient town of biblical fame, Megiddo, known from Revelation 16:16 as Armageddon, used to guard its northern exit during much of the Bronze and Iron Ages.
'En Esur, also En Esur (Hebrew: עין אֵסוּר; [ʕen ʔesuʁ] eh-N eh-s-oor) or Ein Asawir (Arabic: عين الأساور, lit. 'Spring of the Bracelets'), is an ancient site located on the northern Sharon Plain, at the entrance of the Wadi Ara pass leading from the Coastal Plain further inland. The site includes an archaeological mound (tell), called Tel Esur or Tell el-Asawir, another unnamed mound, and two springs, one of which gives the site its name.
A 7,000-year-old Early Chalcolithic large village already showing signs of incipient urbanisation and with an open space used for cultic activities was discovered at the site below later, Bronze Age remains.
