New map of the Megalithic cultures

[Maciamo]

Here is a map of the Megalithic cultures in Europe and North Africa, with the main sites highlighted. There are lots of maps on the web, but none that I found satisfactory as they didn't carefully list all the areas with megaliths.

The oldest sites are dated to c. 6000 BCE in central Portugal and 4800-4300 BCE in Brittany and Andalusia, but megaliths didn't really spread around western Europe until about 4000 BCE, hence the range 4000-2000 BCE for this map.

I have also created a page about the genetics of the Megalithic cultures.
