The Historic Millstone of Idder Banyonger is a 2667 years old piece made by Idder Banyonger, a miller living in Khami.
Considering its age and the quality of the work, people consider it of the highest value.
It is engraved with african patterns and some symbols pertaining to Shamanism.
This piece doesn't exist, but as a legend. It is said that in the year 1376, Shamash-andulli Banyonger, the owner, made use of it in Lisbon to empower the Banyonger family. Now it is lost, or broken, we will never know.
