Every kindergarten wanted the kids (and their parents, of course) to collect them for tinkering. Chestnuts, matches, yarn and acorns were used to construct animals, bracelets and necklaces.
On the other hand, the foresters wanted teenagers to collect them for feeding deers and wild boars during the winter. So, chestnuts were quite rare.
In Bavaria is it a very long tradition to have beer gardens. The landlords have cellars for storing the beer barrels and planted usually chestnut trees above the cellar to keep the cellars cool and to have a natural shadow for the guests during summer. So, it’s quite easy to find chestnuts in Bavaria, where I took all these photos.
