Newgrange

It was constructed without any metal tools around 3200bc which makes it 600 years older than the pyramids of Giza and 1,000 years older than Stonehenge. Every year I enter the lottery to be allowed in at dawn on 21st December when the early morning sun enters the inner chamber for sixteen minutes.... Unfortunately only 24 people fit in. Last year 30,000 applied...
There are 96 kerb stone weighing at least 6 ton each and dragged from the Wicklow mountains.... Some things you should just appreciate and not try to dissect too much....

Will be going back soon. I promised a friend....just saying...
