It’s a nice reconstruction, suggests how remarkable it must have been in its heyday.
There was a dam on the river which made it possible to feed both the drinking water and irrigation needs and fill the large moat which protected the city. In extremis, the dam was breached, the water ran out, and the Babylonians, Medes, and Scythians sacked and ruined the city.
Seems the Babylonians were a little rough on Jews.
Thanks!
Couldn't have happened to a nicer bunch of guys.
