Danes Dyke Flamborough

Danes Dyke was declared a Local Nature Reserve in 2002 in recognition of its wildlife value and its importance to the local community. Local Nature Reserves aim to protect places of special interest and provide opportunities for research, education and informal enjoyment.

The name of this huge earthwork is misleading, in the past it was believed to have been built by Danish invaders, then more recently some archaeologist recorded it as Iron Age. Current opinion is that it was constructed in the middle to late Bronze Age as were many of the defensive/boundary banks and ditches that cover large areas further west on the Yorkshire Wolds, although it is entirely probable that it was later used and modified during the Iron Age and even as late as the 9-10th century AD.
The bank’s construction started with a layer of compacted stones which were overlaid with chalk blocks, rubble and earth and covered over with a layer of turf to a height of between 4-5 metres and a width at the base of about 20 metres. To the west of the bank the ditch, which has become partly infilled over time, is estimated to have been around 3-4 metres deep and up to 12 metres wide. In places the existing single ditch/bank is joined by another smaller bank on the western side, and occasionally a pair of banks.
