Ancient Ruins on the Euphrates

These ruins were north of where we lived. I counted 50 before I got bored. They are spaced out by about 500meters + or - a few meters. If I had to guess Id say that there is 70 of them evenly spaced out with their remains on both sides of the river. One of the pictures is what looks like the remains of a castle in the middle of the river.It almost looks like a watch tower with either tiny window or holes in it.

If they are aquaducts someone was serious about moving some water around in the area.Although you could hardly tell now. (The Roman aquaducts reportedly move about 40 million gallons a day). None of the Iraqis I spoke to knew who built them. I found a short blurb about the Assryians building aquaducts several thousand years ago, but it was stated that they were constructed on the northern portions of the Tigris.I saw no sign of where the stone was obtained. Not all are exactly like the other. Some seem to have steps to the water,but then again theyre all in a different state of disaray.

I saw no other ruins besides these.
