The city's main cathedral is a key attraction for visitors, and one not to be missed; it's a UNESCO World Heritage Site and one of the finest examples of Western architecture.
As well as being a visual spectacle, the site is steeped in history. The cathedral's treasury contains a unique collection of church artefacts which include a silver and gold bust of Charlemagne and the Lothar Cross, dating circa 1000 AD. It has been the coronation place for more than 30 German kings and is the final resting place of the legendary Charles the Great also known as Charlemagne.
The city's magnificent town hall is also worth a visit. Explore this Gothic building and discover mesmerising Carolingian manuscripts, frescoes, and replicas of the imperial insignia, the sword, orb and crown.
