For some reasons - I don't know why - this is called Weihnachtspyramide - even it doesn't have the shape of a pyramid at all. On my post about the Wuerzburg Christmas market is a huge version for outside. This kind of Christmas Dekoration originates in the south of Saxony (southeast Germany, i grew up around the corner) or Bavaria from regions with ancient mining sectors. People in this regions used to be very poor and carving these decorations in the dark, long winter nights created a second source of income for them. Ia not sure if yours come from Saxony or Bavaria (or is made in China - which is possible too nowadays... 😝)
