Enter in the legends of King Arthur and the Holy Grail thou shalt enter the Chalice Well. It is one of the most infamous holy wells found in Britain and Europe.
There is not much known about this Spring as all I heard about it was from locals and that it was one of many springs welling up from the caverns underneath the Glastonbury Tor. Some pointed in the direction of the White Spring and the Red Spring (Chalice Well). Some say it is the Red Spring before Joseph of Arimathea brought the Grail to the Chalice Well turning it Red.
