Q. Aachen Cathedral, a UNESCO World Heritage Site, is located in which country?
Answer: Germany
Notes: Germany's UNESCO World Heritage Site is "Aachen Cathedral". It is Emperor Charlemagne´s own Palatine Chapel, which constitutes the nucleus of the Cathedral of Aachen, located in western Germany. The construction of the chapel between 793 and 813 symbolises the unification of the West and its spiritual and political revival under the aegis of Charlemagne. Originally inspired by the churches of the eastern part of the Holy Roman Empire, the octagonal core was splendidly enlarged in the Middle Ages. In 814, Charlemagne was buried here. The Cathedral Treasury in Aachen is regarded as one of the most important ecclesiastical treasuries in northern Europe; the most prominent inventory items are the cross of Lothar (about 1000 AD), made from gold and inlaid with precious stones, the dark-blue velvet chasuble with embroidered pearls, a reliquary-bust of Charlemagne made from silver and gold, and a marble sarcophagus decorated with a relief of the Abduction of Proserpine, which once contained the body of Charlemagne.
