      Glastonbury Tor: (Avalon, The 'Sacred Heart' of England).

Glastonbury Tor, Avalon. (ancient-wisdom.com)As well as being associated to Avalon, King Arthur, The Holy Grail and Christianity, Glastonbury Tor sits on the St. Michael's Ley, which has a Neolithic provenance, and is known as one of the celtic 'Perpetual Choirs', said to maintain the spiritual integrity of Britain.

The primeval mound (surrounded by water) was a fundamental theme in prehistory, and Glastonbury was surrounded by water until the Somerset flats were drained in the 4th century. The  discovery of lake-villages and raised walkways connecting Glastonbury with the landscape illustrates that the hill was considered worthy of attention since prehistoric times.

   Glastonbury Tor: (St. Michael's Mount, Tor Hill)

The Celtic name of the Tor was "Ynys Witrin," or sometimes "Ynys Gutrin," meaning "Isle of Glass".

Glastonbury Tor is known as the 'Heart of England', revealing a spiritual connection that has been reinforced by association with the Arthurian legend of Avalon, and we are reminded by John Michell that Glastonbury was mentioned in the 'Welsh Triads' as one of ancient Britain's 'Perpetual Choirs'. (2)



Discoveries of Neolithic flint tools from the top of the Tor demonstrate that it has been visited/inhabited since prehistoric times.

The area is known to have once been surrounded by marshland and floodwater. The remains of Iron-age lake-villages nearby confirm this and there are indications that boats could have once sailed right to the 'Tor'. 

705 AD - King Ine founded a monastery here, which became a Benedictine house in the 10th Century.

1184 AD - The church which was built, according to tradition, by Joseph of Arimathea (the man who took Jesus to his tomb), was destroyed in this year.

1190 AD - Monks claimed to have discovered the grave of King Arthur and Guinevere. The grave in the Abbey grounds was discovered after the secret of the burial was revealed by a Welsh bard to King Henry II. The King then informed the Abbot of Glastonbury and, eventually, when rebuilding the Abbey after the fire of 1184 AD, the monks searched again for the grave. About 2m down they found a stone slab and lead across inscribed �hic iacet sepultus inclitus rex arturius in insula avalonia�, which means �here lies buried the renowned King Arthur in the Isle of Avalon�. About 2.7m below the slab was a coffin cut from a hollow log containing the bones of a 2.4m man with a damaged skull, as well as smaller bones with a scrap of yellow hair. The original grave is 15m from the south door of the Lady Chapel. (1).

1278 AD - The bones were re-interred in a black marble tomb before the high altar. (1)

The Abbey Church was built in the 13th and 14th centuries, of which substantial remains still exist.

1539 AD - The Tor was the place of execution of the last Abbot of Glastonbury Abbey, who was hanged, drawn and quartered along with two of his monks.



The 'Chalice' or 'Blood' Well:

A spring-water well. (Also called �Blood spring� because the waters are tinted with iron-oxide). Legend tells how the shaft of the well was built of huge stones by the druids and that later, the Chalice used at the �last supper� (the Holy Grail), was thrown into its waters. Sir Norman Lockyer noted that the style of construction was similar to that seen in ancient Egypt.






Archaeo-Astronomy - Glastonbury lies on the 'St. Michael's ley-line' which crosses the England along the same azimuth as the may-day sun. The alignment is connected through several Christianised ancient sites named after St. Michael and St. George, both of which are known as Dragon-slayers. This combination of serpent and solar worship is reminiscent of William Stuckley's vision of the ancient (megalithic) British landscape. The Tor's association with astronomy is reinforced by extremely accurate geometric connections with Stonehenge.

Alignments - Glastonbury Tor has been identified as a part of the St. Michael's Ley Line or 'Corridor of Incidence', which is astronomical in nature, but it is also part of a vast geometric 'decagon' discovered by John Michell and it forms a right-angled triangle with Avebury and Stonehenge. (Both of these geometric alignments are accurate to within 1/1000th parts). This right-angled triangle also extends north to meet with Arbor Low, which is situated remarkably at exactly 1� east and 2� north of Glastonbury (see below). Glastonbury also lies on the path of numerous ley-lines and several other alignments traversing the English landscape.

The Glastonbury 'Labyrinth'

It is interesting to note that Glastonbury (and the orientation of the tower on top) lies in-line with the St. Michaels Ley, making it a compelling suggestion that the hill was artificially shaped into its present form, an idea which finds favour in the seven-levelled ritual terraced pathway that winds up the Tor. This is suggested to have been a deliberate pathway, either designed to entrap passing spirits, which were believed to travel in straight lines (Ley-lines) or, as a ritual pathway (Labyrinth) for pilgrims.

The spiral pathway was dated by Professor Philip Rahtz to the 3rd or 2nd millennium BC (3).

Glastonbury Tor 'Avalon'. (ancient-wisdom.com)

The area is known to have once been surrounded by marshland and floodwater. The remains of Iron-age lake-villages nearby confirm this and there are indications that boats could have once sailed right to the 'Tor'. 

Navigating the inland sea at Glastonbury - The so-called �Sweet Track�, was discovered in 1970. It extended across the marsh between what was then an island at Westhay, and a ridge of high ground at Shapwick, spanning a distance of almost two kilometres. It is clear that this area was once thus engineered so that it could be passed on foot. It is now known that this was but one of a network of such tracks. Today, the Sweet Track has the honour of being the oldest engineered road in the world and the oldest timber trackway in Northern Europe. Tree-ring dating has concluded that it was built in ca. 3800 BC. The track consisted of crossed poles of ash, oak and lime, which were driven into the waterlogged soil to support a walkway that mainly consisted of oak planks laid end-to-end. Since its discovery in 1970, it has been determined that the Sweet Track was actually built along the route of an even earlier track, the Post Track, dating from ca. 3840 BC. (3)


The Isle of Avalon.

Glastonbury is specifically referred to as Avalon, and accredited as one of Britain's 'Perpetual Choir's' in the 1796 edition of a translation of FABLIAUX (TALES) which includes a four line Welsh text (known as a Triad), and an English translation of it. (7)

According to accounts by the chronicler, Giraldus Cambrensis, the abbot, Henry de Sully, commissioned a search, discovering at the depth of 16 feet (5 m) a massive hollowed oak trunk containing two skeletons. Above it, under the covering stone, according to Giraldus, was a leaden cross with the unmistakably specific inscription Hic jacet sepultus inclitus rex Arthurus in insula Avalonia ("Here lies interred the famous King Arthur on the Isle of Avalon").


Glastonbury geometryArchaeo-Astronomy - Glastonbury is on the 'St. Michaels' ley-line which coincides with the Mayday sunrise, crossing the longest possible stretch of Southern Britain. The 'Leyline' runs from St. Michael's mount in Cornwall to Brent tor, Cadbury, Trull, Creech St Michael, Lyng, Othery, Burrows Mump, Glastonbury, Buckland dingham, Avebury, Ogbourne St George, East Hendred and Bury St Edmonds (All these sites have or had churches dedicated to the dragon-killing Saints Michael and George). From the church of St Michael on the �Mump� at Burrowbridge, (Burrow Mump), Glastonbury Tor is apparently visible behind the intervening hills. Extending this alignment eastward, one arrives at the southern entrance of Avebury.

  It has been observed that from Windmill Hill, at the winter solstice, the rising sun can be seen to roll up the side of the Tor. A  phenomenon that last approximately half an hour.

Avebury/Silbury, Stonehenge and Glastonbury form a right angled triangle (left). The hypotenuse is formed by the  'St. Michaels' ley-line from Glastonbury to Avebury, which coincides with the Mayday sunrise. This same geometry extends northwards to Arbor Low, which sits 2� North and 1� East of Glastonbury.

Glastonbury is 1� West of Mont St. Michel in France. It is also almost exactly 7� South and 4� East of Callanish in Scotland.
