 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 with 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.
