Discover the Ancient Irish Passage Tombs With Your Group


In a country full of ancient Celtic tombs and ruins, Loughcrew is special: it is the largest complex of megalithic passage tombs in Ireland and also one of the oldest. The tombs are spread out between the four hilltops of Patrickstown, Carnbane East, Carnbane West and Carrickbrack. The two major sites of the complex are simply called Cairn T and Cairn L. There are 30 more recorded cairns at Loughcrew in various states of decay and excavation, both below and above ground. The main tombs contain stunning stone engraving, many of which still cannot be translated.


The tombs were discovered by Eugene A. Conewell in 1863, whose claim that there was such a large undiscovered site a mere forty miles from Dublin was initially laughed at. However, he spent the next few years thoroughly exploring the tombs and excavating a large number of cairns. He also established the letter-based naming scheme of the tombs.


A special time to visit Loughcrew is during the dawn equinox alignment in Spring and Autumn. On these dates, the rising sun shines through Cairn T, illuminating the backstone.


Loughcrew is located about 80km north-west of Dublin. To get there conveniently, we can hire a coach for your group. You can then explore Loughcrew and, if you wish, some other ancient sites in the area. Let us know if you need any suggestions for your itinerary.


Pease note, that while access to Loughcrew is free, there is a paid tour groups can take. Contact us and we will book this for you.


This attraction is a brilliant part of our package day trip to the Boyne Valley, which also includes other highlights, such as the Hill of Tara.
