Christmas pyramids (German: Weihnachtspyramide) are Christmas decorations that have their roots in the folklore and customs of the Ore Mountain region of Germany, but which have become popular internationally. They comprise a decorated pyramidal outer frame with candle holders and a central carousel with a rotor at the top which is driven by warm air from the lit candles. The carousel is decorated with nativity scenes and other Christmas figures such as angels and wise men, as well as worldly motifs such as mining folk and forest scenes.
It is suggested that the Christmas pyramid is a predecessor of the Christmas tree. These pyramids are not limited to Christmas: in the Erzgebirge there was a custom of dancing around the "St. John's Tree", "a pyramid decked with garlands and flowers", at the summer solstice. Not actually pyramid-shaped, the Christmas pyramid is a kind of carousel with several levels, some depicting Christian motifs such as angels or manger scenes, and others with more secular motifs such as mountain-folk, forests, and other scenes from the everyday life of people in the Erzgebirge. The spinning motion of the pyramids is traditionally achieved with the help of candles whose rising heat spins a propeller above.
Generally Christmas pyramids are made of wood and based on four- to eight-sided platforms with a long pole in the middle serving as the axle to which the entire apparatus tapers above and which supports any further platforms. Inside in a glass or ceramic support is a driveshaft on to which at least one platform is attached. The figures, which stand on the platforms are also traditionally made of wood.
Christmas pyramids take various forms from intricately carved miniature houses with pitched roofs, to large multi-level structures that simply serve as a display for the carved figures. In many cities in the Ore Mountains there are large Christmas pyramids on the Market Square at the Christmas Market or in other locations associated with Christmas hustle and bustle.
