A Megalith in the Dublin Mountains: Kilmashogue Wedge Tomb

A ruined megalith sitting a bare 100m from a popular car park in the Dublin mountains… this spectacular national monument is only known to a fraction of passers-by.

Kilmashogue Wedge Tomb
I’m almost loathe to tell anyone about this place… it’s such a wonderful little secret, tucked away beside the car park at Kilmashogue. To reach it, head up the steps from the car park. At the top step, veer right slightly across the road, and up a steep leaf-strewn path. At the top, you’ll find the remains of 4,000 year old tomb.
Not so long ago, this would have been sitting on a bare mountain, with its boulders gradually taken away for stone walls and the like. These days it sits in a perfect circle of of birch and conifers, with a perfect ceiling to the sky above.
The place has presence. I’ve brought many people there to visit, at day and night… few have have denied the apparent power of the place. While I love the Dublin Hills, I often get a sense of a dark mood about the place… it’s such a liminal zone… wild country in view of the city. It’s like the dark conscience of the metropolis. This little sacred of trees, however, has a constantly positive atmosphere
I often pass by the area at night with friends, as we’re heading off mountainbiking up to Three Rock in the dark. The car park is often full of parked cars, their internal lights on and the windows steamed up. Mating rituals performed, and marital vows broken.
‘Map 5 Q12; OS1/2″ 16 0.15.25
A Megalithic gallery-grave allied to the wedge-tombs; it consisted of a roughly rectangular chamber and a small ante-chamber set in an oval mound of stones, dating probably to the earlier part of the second millennium B.C. Later in the same millennium burials took place and a fireplace was constructed.’

  1. The site is probably more well known than you think, most people just couldn’t be assed !
    It’s a nice spot all the same even if the magic is a bit lost by the sound of cars driving around ! Did you know there is another one up Three Rock Mountain ? It’s in the trees on Two Rock – now that’s a place not so many people know about.

  2. I’ve never actually made it to the one on two rock. I know it on the map, but have never tracked it down. Is it easy to find?
