One of the most magical spots in Ireland, Newgrange is a Neolithic monument dating back to approximately 3200 B.C. and shrouded in mystery to this day. Nearly 280 feet wide at its widest point, the circular monument has an inner stone passageway and chambers containing human bones, as well as items thought to have been grave goods and votive offerings. According to Irish folklore, Newgrange is a home for the Gaelic gods, and many historians believe that it may have historically had some sort of religious significance due to the fact that its entrance lines up with the winter solstice sunrise.
