It's hard to know what people remark on more when they visit the Burren: the flowers or the walls. Dry stone (i.e. unmortared) walls are everywhere. They lead the eye across hillsides and they carve up sunset skies like Japanese lacquer screens. They come in many (subtly) different styles of construction and some date back to the first Neolithic settlers of the Burren. This picture was taken at 10pm, in June 2004, on the high hills of Gleninagh above Ballyvaghan, looking West to the Atlantic.
