Cup stones from Plontabuora
The shell stones of Plontabuora are located on the Collina Plontabuora southwest of Ruschein in the Surselva , in the canton of Graubünden in Switzerland .
On the southern slope of the Collina Plontabuora there is evidence of a settlement from the Middle Bronze Age . Excavations to the west of the ruins of Frauenberg Castle revealed dry stone walls, shards of vessels and a 19 cm long bronze needle.
On the hill, in the upper part of the Plontabuora special forest reserve , there are around two dozen megalithic shell stones from Ilanz Verrucano with shells between 4 and 30 cm in diameter and 4 to 10 cm deep. Their age cannot be precisely determined. Presumably they were used as places of worship by the residents of that time. For some stones there are signs with information on possible use.
