St Winifred’s Well, Holywell, Wales
If you have ever read or watched Cadfael (and if you haven’t, you should), you may remember this. As the story goes, Winifred was decapitated after rejecting the advances of a suitor in order to preserve her virtue, which already made her pretty holy, as far as the medieval Church was concerned. When she was subsequently restored to life, it was naturally decided that she was a saint, and the spring which appeared on the spot of her miraculous revivification became an important pilgrimage site. Many credulous people still visit the shrine today to bathe in the healing waters. The current architecture dates from the late fifteenth century.
