Back to prehistory:

a good, long page on Kurgan culture (maybe the original ProtoIndoEuropeans, N of the Black Sea, southern Ukraine and Russia, 5000 BC and after.

Another early IndoEuropean settlement (before 6000 BC) was Catal Huyuk in central Turkey.

The Neolithic Landscape of Çatalhöyük. If you have any interest in this at all, you should keep touring through the subsequent 5 pages (follow the next button in the upper left corner). Fascinating stuff (at least to me).
