I've created maps of the cairns at Sliabh na Caillighe/Loughcrew, using Bing Maps. The cairns are believed to be older than Newgrange, dating possibly to 3500BC, and were given letter designations by Eugene Conwell, who excavated some of them in the 1860s. The hill known as Carnbane West today was, according to local folklore, known previously simply as Carnbane (from carn bán, the "white cairn"). The hill labelled Carnbane East today was known in the past as Sliabh na Caillighe, the Mountain of the Hag.
The best known of the cairns are Cairn T, called the Hag's Cairn, which is aligned towards sunrise on the equinoxes, and Cairn L on Carnbane, which is aligned towards sunrise at Samhain (November) and Imbolc (February).
For more on the Samhain alignment of Cairn L, see this page.
For more on the equinox alignment of Cairn T, see this page.
Don't forget to watch the video below, in which I give a quick overview of the hills of Loughcrew using Google Earth. This will give you a sense of where the various cairns are located and which are considered the principal peaks. It will also give you a good idea of the location of the cairns in relation to the Brú na Bóinne complex (Newgrange, Knowth and Dowth):
Above is a short video showing you the basics of the National Monuments Service online interactive map of all known recorded monuments in Ireland. It is an extremely handy and useful resource and one which is relatively easy to use. The video is a short introduction to finding information about a site or monument in your locality.
Above is a short video showing how I put together the new Boyne Valley Ancient Sites Interactive Map for Mythical Ireland. I quickly show how the map was compiled layer by layer, with different features being added along the way. The map is fully interactive - you hover over each site or feature with your mouse and a text box pops up explaining what that particular monument or feature is. A lot of the sites are also clickable, leading to further content. The new map features lots of newly-discovered monuments and landscape features, including a large raised routeway running from Dowth towards Site Q, the Dowth Henge, and the Dowth cursus which runs away from Dowth passage-tomb towards Ballyboy Lake.
The huge range of sites in the valley featured on the map include passage-tombs, mounds, barrows, possible passage-tombs, embanked enclosures, ringforts, earthworks, standing stones, ritual ponds, a destroyed stone circle, and more.
