Topped by an octagonal tower, Mainz’ immense cathedral, built from deep red sandstone in the 12th century, is quintessentially Romanesque. Its predecessor went through a literal baptism by fire when it burned down in 1009 on the day of its consecration. Over the centuries seven coronations were held here. Sunday hours can vary.
