The motifs on the Hanging Stones (or Hangingstones) rock were first recognised as important prehistoric carving in the 1860s when the area was being cleared / stripped in preparation for quarrying. Bedrock from around the carvings was quarried away leaving the remnants of the carved bedrock in situ.
Unfortunately, the Hanging Stones has since suffered various graffiti attacks, the addition of a Celtic knot and even people hammering quartz pebble inclusions out in 2013.
The model shows the 6 x 4 metres carved westerly section of bedrock as it stood on 31 March 2009. It was created from 132 vertical photos captured using a SfM leaning stereo photogrammetry approach as part of my research for the Historic England publication “Application of Microsoft Photosynth within Heritage”.
In July / Aug 2012, the Hanging Stones suffered another major graffiti attack which unfortunately impacted some of the prehistoric carvings towards the centre of stone.
