The Ancient City of Ur
As I was on my back to the States for leave I had the opportunity to stay at Tallil, which is a Coalition Forces base in southern Iraq.  Just outside of the base is the ancient City of Ur.

A little history about Ur.  It is located in the southern part of Mesopotamia, where the mouth of the Euphrates and Tigris Rivers was.  Their courses have changed since that time.  It is thought to have been the largest city in the world from 2030 to 1980 B.C.  It is thought that the first use of the wheel took place there.  It is pretty much identified now by the Ziggurat.  The Ziggurat is a temple dedicated to the moon god of Sumerian mythology, "Nanna."  Ur is also mentioned in The Book of Genesis as the birthplace of the prophet Abram (Abraham).  There are remains of a royal palace, houses, and a rebuilt Abram's house.

It was pretty cool to be walking around a city that's over 4,000 years old.
The Ur Ziggurat.  In it's day, it was taller.  There was a temple built atop of this structure.  There was also an arched entranceway at the top of the stairs.
Another view of the Ziggurat.  What you see in the foreground is the remains of the Royal Palace.
