Aachen Cathedral

Charlemagne made the Frankish royal estate of Aachen, which had been serving a spa ever since the first century, his favourite abode. The main buildings of the Imperial Palace area were the Coronation Hall (aula regia – located in today´s Town Hall) and the Palace Chapel – now Aachen Cathedral. The Palatine Chapel is based on an octagonal ground plan, which is surrounded by an aisle and by tribunes above, and roofed with a dome. Facing the altar, the Emperor sat on the gallery; the Carolingian stone throne was the coronation seat of the kings of the Holy Roman Empire of German Nation from the Middle Ages until 1531. The chapel itself is easily recognizable from later additions by its distinctive structure. An atrium on the western side and a portico led to the imperial apartments. The Gothic choir and a series of chapels that were added throughout the Middle Ages created the composite array of features that characterised the cathedral.
