On our recent visit to the east coast Jon and I visited Duggleby Howe, a large green 'hump' in the landscape. We drove past it at first, then had to retrace our steps.
Julian Cope writes in his book 'The Modern Antiquarian',
'Excavations in 1890 revealed that the mound was built above a rectangular rock-cut shaft ten feet deep. No burial was discivered, but a large double grave of ten bodies was found in a central pit-grave, along with a fine flint knife, stone arrowheads, and bone pins. Later, fifty Beaker cremations were inserted into the mound alongside more bone pins and arrowheads.
Duggleby used to be surrounded by a deep ditch and high bank so large that the local B1253 now cuts right through it.'
