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. The plans, drawn by Odo of Metz, were part of the programme of renovation of the kingdom decided by the ruler. Today much of the palace is destroyed, but the Palatine Chapel has been preserved and is considered as a masterpiece of Carolingian architecture and a characteristic example of architecture from the Carolingian Renaissance.
