The Palatine Chapel in Aachen is an early medieval chapel and remaining component of Charlemagne's Palace of Aachen in what is now Germany.

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.

The Palace of Aachen was a group of buildings with residential, political and religious purposes chosen by Charlemagne to be the centre of power of the Carolingian Empire. The palace was located at the north of the current city of Aachen, today in the German Land of North Rhine-Westphalia. Most of the Carolingian palace was built in the 790s but the works went on until Charlemagne's death in 814.
