One of the most intriguing stories about the cross (hinted at but not explained on the Bucks CC website) is that the present day cross shape was originally a large phallic shape. The Bucks CC site mentions that it has almost certainly been altered since the 18th C; I can imagine what both the Church and pious villagers in the Vale below had to say about a hundred foot dick in full view every day. I only wish there was evidence for the original shape, so they could spend their 75,000 quid restoring it to that!
