At the eastern tip of the island are the ruins of a small 12th-century church with a beautiful Romanesque door on its southern side. Inside are six extraordinary Celtic stone figures , thought to date from the 9th century, lined up along the wall like miniature Easter Island statues.
This line-up is a modern arrangement; most of the figures were discovered buried in the walls of the church in the 19th century, where the medieval masons had used them as ordinary building stones. The six main figures, all created by the same hand, are flanked on the left by a sheila-na-gig (carved female figure with exaggerated genitalia), which is probably contemporary with the church, and flanked on the right by a scowling stone face. The age and interpretation of these figures has been the subject of much debate; it has been suggested that the two central pairs, of equal height, were pillars that once supported a pulpit, and that they represent either saints or aspects of the life of Christ.
