Some locals still carry out a pilgrimage known as the Turas to the Well of Enda (also known as 脡inne or Endeus), a bubbling spring in a remote rocky expanse in the southwest. The ceremony involves, over the course of three consecutive Sundays, picking up seven stones from the ground nearby and walking around the small well seven times, putting one stone down each time, while saying the rosary until an elusive eel appears from the well's watery depths.
If, during this ritual, you're lucky enough to see the eel, it's said your tongue will be bestowed with healing powers, enabling you to literally lick wounds better.
