Today the chapel is part of Aachen cathedral. The landmark was the first German memorial to be listed as a UNESCO World Heritage Site. Visitors to the cathedral can also see the Emperor's burial place and his grand throne. But Aachen is also known for other local sights and specialties, like its hot springs and "Printen" cookies, which are popular at Christmas time. For visitors who want to move beyond Aachen's time-tested traditions, there's also the Ludwig Forum, where an exhibition of avant-garde art titled "Nie wieder störungsfrei!" is on display through February.
