More information : [Area: ST 5150 3860] On and around Glastonbury Tor are evident traces of earthworks, but not in any regular form. (1)
A/P's show lynchets in the field called 'The Lynches' east of Tor Hill. (2)
'Test holes and auger holes were dug on all the loweer slopes and terraces of the Tor. In all cases they revealed only clear yellowish soil and silt lying on bedrock down to 4 ft. While their evidence cannot be regarded as conclusive, nothing was found which would justify further exploration of these areas'. (3)
The terraces on Tor Hill (centred ST 51153856) are probably medieval. They are more pronounced on the lower slopes of the Tor, but lose some definition higher up partly from pathways and landslip.
The 'Lynches' (ST 51643853) are well defined terraces; again, probably medieval. (4)
The conventional explanation of the lynchets and terraces is that they are either natural features or strip-lynchets; 'but a theory has recently been put forward by Mr G N Russell that they are, in fact, the remains of a three-dimensional maze. The argument is complex, but it is worth consideration; if this were true it would be of the greatest importance in any consideration of the religious aspects of Glastonbury'. (5)
The original and generally most accepted view of the earthworks was that they were Medieval strip lynchets. However it is pointed out by Philip Rahtz that the upper portion of the Tor is incredibly steep and it would have been very difficult to adequately cultivate the strips with or without animals. It is argued that there would have had to have been a huge shortage of food so that people were forced onto marginal land. It is however known that the terraces were used as lynchets as late as the 19th cebtury, and a drawing of 1670 clearly shows the lower terraces being used for cultivation where as there is a sharp contrast with the upper terraces which are much more wild. A survey undertaken on behalf of the National Trust in 1999 effectively 'disproved' any chance that the terraces are differential erosion due to the natural geology.
While the idea that the terraces are a mizmaze is still a prominent one in popular culture, it is very unlikely to be the case. It would be unusual to place a maze on such long hill and there is too much subjectivity in interpreting the shape of the terraces. One idea suggested by Rahtz is that the terraces actually originated in the Neolithic period. Barrett has pointed out that the Neolithic was the advent of monumentality but also of modification of natural features. The Tor is highly visible from anywhere in the landscape and as such would have been a significant landmark. It is then argued that the Neolithic modifications were reworked into lynchets as and when they were needed, although the upper levels were too steep for such use. It remains the most likely explanation that the terraces have a history of re-use deviating from their original purpose. (6)
