Palatine Chapel
The Palatine Chapel of Aachen was built between 792 and 804 by Odon of Metz (742-814). It was Charlemagne's private chapel in Aachen, which was part of his palatine complex. It contains the remains of Charlemagne and was a place of coronation for about 600 years. In the 21st century, the chapel has been preserved almost intact, despite later additions and major repairs in the 19th century. As part of Aachen Cathedral, it is included in the UNESCO World Heritage List.
