The Most Impressive Megalithic and Prehistoric Sites of Ireland

Not Just a Bunch of Stones in the Middle of Nowhere, I'm Telling You!

Megalithic Ireland is timeless, and pre-historic Irish monuments are a visitor magnet even millennia after it was forgotten who built them and why. Many visitors to Ireland are drawn towards the numerous megalithic and prehistoric artifacts on the island. Built a few thousand years ago by persons unknown, with an intention we know nothing of, they still hold a certain fascination today. Be it because of the sheer impact on the landscape,  because of the building works necessary at the time, or the (often just supposed) mystical background. But what actually are the best monuments to visit?
