Chalice Well  The Chalice Well, also known as the Red Spring, is a well situated at the foot of Glastonbury Tor in the county of Somerset, England. The natural spring and surrounding gardens are owned and managed by the Chalice Well Trust (registered charity no. 204206), founded by Wellesley Tudor Pole in 1959. Research by Exeter University School of Geology in 2009 found that the Chalice Well is fed by a deep aquifer in the lower levels of the Pennard Sands. Archaeological evidence suggests that the well has been in almost constant use for at least two thousand years. Philip Rahtz found several dozen flints from the upper Paleolithic and Mesolithic, and a sherd of Iron Age pottery nearby. Roman and medieval sherds were also found in more recent layers. Water issues from the spring at a rate of per day and has never failed, even during drought. Iron oxide deposits give water a reddish hue, as dissolved ferrous oxide becomes oxidized at the surface and is precipitated. Like the hot springs in the nearby city of Bath's Roman built baths, the water is reputed to possess healing qualities. Another spring, known as the White Spring, emerges slightly east of the Chalice Well or Red Spring. The water from this comes from a shallower aquifer and is colourless. A building, originally a waterworks, has been built over it. This building now serves as a place of worship and visitors are admitted at irregular opening times. In addition to the legends associated with Glastonbury, the Well has been portrayed by 20th-century writers as a symbol of the female aspect of deity, with the male symbolised by Glastonbury Tor. It is a popular destination for pilgrims in search of the divine feminine, including Neopagans. The Well is however popular with all faiths and in 2001 became a World Peace Garden. Wells often feature in Welsh and Irish mythology as gateways to the spirit world. The overlapping of the inner and outer worlds is represented by the well cover, designed by the church architect and archaeologist Frederick Bligh Bond and presented as a gift after the Great War in 1919. The two interlocking circles constitute the symbol known as the "Vesica Piscis". In the well lid design, a spear or a sword bisects these two circles, a possible reference to Excalibur, the sword of the legendary King Arthur, believed by some to be buried at the nearby Glastonbury Abbey. Foliage represents the Glastonbury Thorn.
