The Cathedral is another key attraction for visitors, and not one to be missed – it’s a UNESCO World Heritage Site and one of the most famous examples of Western architecture.
As well as being visually stunning, it’s a site steeped in history. The cathedral treasury contains a unique collection of church artefacts including a silver and gold bust of Charlemagne and the Lothar Cross (dating from around 1000 AD). It has been the place of coronation for more than 30 German kings and is the final resting place of the legendary Charlemagne, also known as Charles the Great.
Aachen's magnificent town hall is also well worth a visit: you can explore this Gothic building and discover mesmerising frescoes, Carolingian manuscripts and replicas of the imperial insignia - the sword, orb and crown.
