Graculus: I have archived this cache due to it's placement within an archaeological site. I will gladly unarchive if the owner wants to move it to a better location.
The guidelines state that caches should not be placed "in areas which are highly sensitive to the extra traffic that would be caused by vehicles and humans (examples may include archaeological or historic sites)."
The Geocaching Association of GB guidelines also state "No cache should be placed in such a way as to risk damage or disturbance to any Site of Special Scientific Interest (SSSI) or Scheduled Ancient Monument (SAM)"
