The now-roofless church in Kilnaboy, County Clare is similar to many others in the region, dating from the 11th century with subsequent additions such as the late-mediaeval east window (seen above). One unexpected feature of the building can be found over a door on the south side: a Sheela na gig. For those unfamiliar with these figures, of which around 100-odd exist in Ireland, they are believed to be fertility symbols which first appeared in this country during the 12th century, perhaps introduced by Anglo-Norman settlers.
