Interior of the Palatine Chapel in Aachen, Germany

A resurgence of architecture in the West began in the 800s which looked back on Roman traditions and was also influenced by Byzantine and Oriental work. The Palatine Chapel was part of the emperor's great palace complex. Designed by Odo of Metz, the essential structure of the building is Roman. This is apparent in the tunnel and groin vaults and the high octagonal vault. The chapel resembles S. Vitale with its octagonal inner core. The ornamental details are also Byzantine.
