Barbarossa chandelier

The Barbarossa chandelier (German: Barbarossaleuchter) was made on the order of Emperor Frederick I, nicknamed Barbarossa, and his wife Beatrice sometime between 1165 and 1170 and was installed under the cupola of the Palatine Chapel in Aachen Cathedral. The chandelier was a donation in honour of Mary, Mother of God, the patroness of Aachen Cathedral and simultaneously represented a tribute to the builder of the cathedral, Charlemagne.
