Located in present-day western Germany and consecrated in 805, Aachen Cathedral is one of Europe’s oldest and was built under the orders of Charlemagne. The Holy Roman Emperor was buried here after his death in 814, and the cathedral also served as the coronation site for 31 kings and 12 queens of Germany between the years of 936 and 1531. Built mainly in the Carolingian-Romanesque and Gothic styles, with a bit of Ottonian influence, the church’s interior is even more intricately detailed than its exterior and notably contains the throne of Charlemagne.
