Aachen Cathedral is an exquisite example of a historic Christian church established in Aachen, Germany. Constructed by Emperor Charlemagne, it dates back to 796 and exhibits two distinct architectural styles - Carolingian-Romanesque and Gothic- along with parts of the Ottonian style. The Palatine Chapel, which serves as the core of the cathedral, was modeled after San Vitale in Ravenna and Charlemagne was buried there in 814. The cathedral has seen the coronation of 31 German kings and 12 queens and was declared a UNESCO World Heritage Site in 1978 due to its artistry, architecture, and importance in the history of the Holy Roman Empire. It also houses notable works including the Throne of Charlemagne, Marienschrein, Barbarossa chandelier, Pala d'Oro, Organ and Bells. Time Magazine described it as "one of Europe’s oldest treasures" and showcased the beauty of this venue.
