Have you ever heard of a Neolithic necropolis? I hadn't either until my children and I visited the Brú na Bóinne site north of Dublin, Ireland.

We took a day trip to the Boyne Valley where ancient burial tombs are found in a group called a necropolis, or cemetery. Brú na Bóinne includes Newgrange, Knowth, Dowth and Townleyhall.

The tombs are older than Stonehenge in England. They were constructed in 3500 BC, which was 4000 years before the Anglo-Norman castles were built in Ireland and six hundred years before the Pyramids were built in Egypt.

The passage tomb mounds attract 200,000 visitors each year. If you have the chance to travel to Ireland, you, too, will want to make a trip to see these amazing prehistoric structures!
