Newgrange

Brú na Bóinne is a prehistoric sites complex designated as a World Heritage site in 1993 by UNESCO. It is Europe's largest and most important concentration of prehistoric megalithic art situated on the north bank of the River Boyne 50 km north of Dublin, capital of Ireland. Brú na Bóinne consists of three main prehistoric sites. Among which, the megalithic tomb of Newgrange is the most famous of a number of passage graves in the area. Dated to around 3200 BC, Newgrange is 1,000 older than Stonehenge and centuries older than the great pyramids of Egypt. There is no agreement about what the site was used for, but it has been speculated that it had religious significance – it is aligned with the rising sun and its light floods the chamber on the winter solstice.

Thanks a lot for helping me with my UNESCO postcard collections, Dear Ana! :) The two postcards of Newgrange and the stamps are both awesome. The noteworthy mysterious patterns of these big stones shown on the photos are still unsolved and no more can convinces others what exactly they mean.
