During Cromwell's campaigns in Ireland one of his generals said of the Burren "There isn't tree to hang a man, water to drown a man nor soil to bury a man". And so the residents were spared from Cromwell's protestant crusade. It's a very apt description. Nothing of any size can grow in the limestone sheet the forms the surface of this entire area, on short grasses and wildflowers. Even so, some of the oldest historical monuments in Ireland can be found in this area, dating back an incomprehensible 5 millenia, to when the Great Pyramids were still under construction.
In modern times, few people live in the Burren. Those that do are mostly Irish speakers.
It is an ancient Celtic Ring Fort. This Fort and other sites like it would have been inhabitied from around 500 A.D. to 1,500 A.D. in Ireland At the fort they have a 4 part tour. The first part is a display area which gives you some back round information on the Burren and the various sites in the area.The second part is a very nice film which tells you a bit about the Burren and gives you information on the other forts and tombs in the area. The 3rd bit is a virtual tour. It's a kind of 3D cartoon which shows you what a day was like for the people who lived in the fort - it's only about 7 or 8 minutes long but you understand the whole thing so much better after seeing it.
The last bit is the tour of the fort itself - they give you a little map and you can actually walk around the site and see it as it is today. It's interesting to compare with the other forts and having seen the virtual tour it's easy to visualise where everything would have been. If you are in Clare or the Burren go see it - and try the coffee - it makes all the difference to get fresh ground coffee on a cold spring day!
Near the Cliffs of Moher, there are many signs warning visitors to stay back from the edge. While many people choose to ignore this wise advice, beware that the signs are there for a reason, as people have fallen off. The death toll is rumoured to currently be around a dozen.
