This is thought to be the site of an early medieval chapel or keeill.  A natural hill at Cronk y Croghee now has a flat top where a Wesleyan Chapel stood during the 19th century. There is now no trace of a building here.


Two 12th century slabs were discovered buried in Cronk when the hill was being lowered some years ago for the improvement of the highroad which cuts through its western side. They are amongst the carved stones now displayed in St Michael's parish church.
