Sheela-na-Gigs are carvings of naked females, posing in a manner that is usually described as 'exhibiting' themselves and are often called 'obscene' images, so it is rather surprising that they are found on churches and other religious structures. Even more surprising is the fact that they are not hidden or put somewhere they could be missed, but are usually placed in the most prominent and visible positions where everyone could see them such as above the main doorway or over a prominent window. It appears that those strange enigmatic Sheela-na-Gigs are not merely fascinating curiosities but extremely important archaeological artefacts that pose important questions about the culture of the period within which there were created and the true nature of Christian religion that existed during the Middle Ages.
