While explicit sexual imagery is often found in the sacred architecture of other cultures (for example Erotic Indian Temple Sculptures), it is less commonly associated with Christian churches. But it is not absent altogether, particularly from the exterior of ecclesiastical buildings. One image that is fairly common is the Sheela na gig, depicting a naked woman holding open a gaping and exaggeratedly large vulva. Another example is shown in the image here, of a male figure performing an explicit act of autofellatio – in other words, sucking its own penis. This sculpture can be seen on the facade of Cologne Cathedral in Germany, where it is supporting a statue of the 13th century Archbishop Konrad von Hochstaden.
