Such an interesting artefact just sat under some guy's barn... can't help but wonder how many more items like this there are out there, and how many of them we'll never find before they're accidentally destroyed.
to find new artifacts the best hope is to look for historical sites that have not been built over already. what i find interesting here is that now with aerial and satellite images and AI search we are able to detect such sites even when they would otherwise be unnoticed by the human eye.
My favorite in Czechia was a married pair that decided to build their family house on a plot not far from the Southern Moravian city of Znojmo (2007). They started digging the foundations ...
... and found out that their future home is going to be located in the outer zone of a huge necropolis from the 8th and 9th century. Several hundred silent neighbours at the least.
