Mainz Cathedral

The most obvious item on our list is Mainz Cathedral, which is considered one of the best examples of Romanesque architecture in Germany. Its six towers puncture the sky of Mainz’ city centre and overlook the picturesque old town market square. The ancient walls are rooted in 975 and safeguard the tombs of princes and archbishops, while the Treasury houses a precious collection of ecclesial art and décor. If you want to learn more about the cathedral’s history, it’s worth checking out the exhibition of the on-site museum.
