The final programme in an eight-part series in which Professor Aubrey Manning seeks to solve some of the enduring mysteries of the British landscape through clues in geology, archaeology and natural history.
`For many years, one of the mysteries surrounding Glastonbury has been the origin of a series of stepped terraces on the tor. Were they part of a Neolithic worshipping ground, and are they a clue to the myths and legends which have long been linked to Glastonbury?
Having established that the terraces are not natural features, Aubrey talks to historian Ron Hutton about the idea that the terraces could be a maze, created by Neolithic people.
Aubrey next examines the idea that the terraces were linked to fortifications on the tor, perhaps associated with the legend of King Arthur.
A new geophysical survey of one of the terraces, carried out by Meg Watters, has found no evidence of fortifications or any other kind of building on the terraces.
Aubrey concludes that the terraces were created for strip farming by the monks of Glastonbury Abbey. They had already drained and reclaimed the Somerset Levels to provide pasture and the terraces would have given them valuable dry arable land.' [Open University Wordlwide website].
