The remains of the town, dubbed al-Natah, reveal how life at the time was slowly changing from a nomadic to an urban existence, archaeologists said.

Summary: Archaeologists have discovered a 4,000-year-old fortified town, al-Natah, in an Arabian oasis. The town, home to up to 500 residents, suggests a transition from nomadic to urban life during the early Bronze Age. The discovery of al-Natah challenges the notion that northwest Arabia was barren desert during this period.
