A good 6,000 years old huh? Hm....that's a lot older than those Egyptian pyramids isn't it?:D     You know there had to be dozens of these things all over the British Isles in ancient times. But since most were built of wood they have since rotted away. I think the main reason why so much more ancient architecture and signs of ancient civilization are found in places like the Mid-East and North Africa is because those structures have survived longer because they built with stone because that's what was available. Whereas in Europe they tended to build with wood because lumber was abundant. You make use of what you've got.    :clink to the Isles, although American, I am of the ancient island race myself:cool:(and German;)).
