Sorry you had difficulty finding this Drew, this is why we have given a rating box for the accuracy of the coordinates. Unless the site has a rating of 4 or 5, then you have to be careful and not just follow the coordinates "blindly". Sometimes, in the days before the accuracy rating, a comment will have been written as a note in the description.
Many of the sites on the portal have been added with only the nearest village or an approximate position given, after finding of their existance on a basic map or in a historical monument record. This is then the fun part of hunting them down in real life.
Often in France these sites may be marked on the 1:25000 ign maps which can be called up for the area via one of the blue buttons at the top of the site page to give better info, but certainly not in all cases. Often, it requires much more persistance to find the site, and a trick I use in France is to go to the local Mairie if the community is known, and they sometimes have a map outside, with local monuments and features marked on it, or perhaps a series of suggested walks. Sometimes the name refers to a "lieu dit", perhaps a farm name, in which case you can find that on the map, then have to hunt around using your stonehunting sense, or ask a local.
Sometimes, but not in this case, the site is one I hunted down during my trip in 2005, but have still to get round to adding my info on here, which is unfortunately the case for several hundred sites!
Something is not right. This message is just to keep things from messing up down the road
