Dom (Cathedral)
Unmissable in every sense, this behemoth is one of the most awe-inspiring buildings in the world and holds a number of treasures, including the golden casket holding the remains of the Magi, the ninth-century Gero crucifix, the Stefan Lochner triptych and medieval stained glass windows. Climb the 509 steps to the viewing platform of the 157m- (515ft-) high South Tower for the dizzying views and down below look in the Schatzkammer (Treasury Museum).

Romanesque Churches
The city boasts 12 wonderfully atmospheric churches, largely unassuming from the outside, which were originally built between the 10th and the mid 13th centuries, then rebuilt and restored after severe war damage. Don't miss Gross St Martin, St Aposteln, St Gereon, St Maria im Kapitol, St Cäcilien (now home to the Schnütgen Museum of Sacred Art) and especially St Ursula with its amazing and macabre Goldene Kammer bone chapel and reliquary room.
