Willershausen is a village in the Northeim District, Lower Saxony, and part of the Kalefeld municipality.
Throughout the Middle Ages the Fulda monastery held fief rights in Willershausen village, so that in modern times a cross symbolising Fulda was integrated in the coat of arms of Willershausen village.
The raw material of the brickyard was clay which stemmed from a nearby Open-pit mining site.
[2] Among the fossils that were found are parts of Mammutidae, Giant salamander, fishes and ostracods, too.
The former clay mine is a landmark of the Harz – Brunswick Land – Eastphalia National Geopark since 2012.
