Nanteos Cup
Welsh: Cwpan Nanteos
The Nanteos Healing Cup, The Tregaron Healing Cup
A medieval wood bowl which were held at Nanteos Mansion near Aberystwyth in Wales for many years, before that it had been in the possession of the abbey at Strata Florida (founded in 1164). It's crafted from wych elm in the late Middle Ages. Today less than half the bowl remains due to damages over the years, but it should have been 10 cm in height and with a diameter of 12 cm.
In the late 19th century it was said it could heal those who drank from it, and it contained a piece of the True Cross. Because of this it in time got onto the list as a candidate to be the Holy Grail - among with about two hundred other items in Europe.
