Newgrange is a prehistoric monument located in County Meath, Ireland. It is a circular mound with a stone passageway and chambers inside, and is surrounded by 97 kerbstones with elaborate carvings.

Newgrange is believed to have been built around 3200 BC, making it over 5,000 years old. It is older than Stonehenge and the Egyptian pyramids, and is considered one of the most important prehistoric sites in Europe.

The purpose of Newgrange is not entirely known, but it is thought to have been used for rituals and ceremonies. One of the most interesting features of the monument is the alignment of the passageway and chambers with the sunrise on the winter solstice. This allows a beam of sunlight to enter the passageway and illuminate the central chamber on the shortest day of the year.

Visitors to Newgrange can take a tour of the monument and learn about its history and significance. The site is managed by the Office of Public Works, and guided tours are available year-round.

In addition to the monument itself, there are also several other prehistoric sites in the surrounding area, including the Hill of Tara and the Boyne Valley, which are also worth visiting.

Overall, Newgrange is a fascinating and awe-inspiring site that offers a glimpse into the lives of our ancient ancestors. It is a must-see for anyone interested in history and archaeology, and is a unique and memorable experience for any visitor to Ireland.
