Charlemagne had Aachen built up into his favorite residence. From here he ruled over his huge empire, which stretched from the North Sea to the Mediterranean. In 2014 Aachen is commemorating Charlemagne, who died there 1200 years ago. With the imperial cathedral as its focal point, special exhibitions with sumptuous objects from all over Europe bring Charlemagne's era to life.
