This is probably the most famous well in Wales. It is said that the water holds a cure for rheumatism. On the eighth Sunday after Easter, it was the custom for young people to sprinkle themselves with the water from the spring and dance.

The area of the pool was also said to be haunted by a Grey Lady.
