Self taught archaeologist Alexander Keiller re-erected over 50 fallen stones at Avebury in the 1930s in an attempt to authenticate the site.
But his attention focused more on the preservation of the stone circles than the archaeology beneath the ground. He excavated large areas around the stones and lost much of the buried history when he concreted them in place.
This is not a new concept: the stones at Stonehenge are not so much standing as founded into the ground. These megaliths were stabilised in the same way just after the First World War when they showed signs of leaning.
