“Dolmen du Mont Ubé”
This is a Neolithic passage grave in Parish of St Clement, Jersey.
When it was discovered it 1848, the capstones were blasted and removed by quarrymen for building materials. Inside were found human bones, urns, axes and a polished stone pendant. The local farmer who was responsible for the blasting then used the remaining upright stones as a pigsty until it was reclaimed as a historic site.
