"This Dolmen was fashioned after the famous Poulnabrone (The Hole of the Sorrows) Dolmen, Co. Clare.
After extensive research (!!!!!!!!! my exclamation marks!) and engineering it was erected by our very own David K. Sproule of the Fever River Stone Company, Galena, Ill. A stonemason of reknown whose Irish ancestry hailed from Castlederg, Co. Tyrone, Ireland and later settled in Galena Illinois, February 1836."
The tourists will be so dissapointed when they see the real thing, not nearly as lovely I'm sure you'll agree: http://www.themodernantiquarian.com/post/38102
