Megiddo was a royal city of the Canaanites, the most famous battlefield in the world.  Thutmose II who battled with Megiddo in 1468, said "Taking Megiddo is like taking a thousand cities."   Megiddo laid in a strategically important place.

Excavations of Megiddo reveal  20 cities -each built on the ruins of the preceding one dating back to 400 BC.

Megiddo means Armageddon, and many people think this is where the Battle of Armageddon will take place.    "And he gathered them together into a place called in the Hebrew tongue Armageddon."  Revelation 16:16
