Duomo di Magonza (975-1036): brucia il giorno stesso della consacrazione, e verrà ricostruito altre sei volte

L’arcivescovo Willigis fece iniziare nel 975 un duomo ispirato a San Pietro a Roma, degno del rango imperiale della sua sede. Il 29 agosto 1009, proprio il giorno della consacrazione, un incendio lo distrusse. Ci vollero quasi tre decenni per ricostruirlo: sarà solo il primo di sette incendi che il duomo di Magonza attraverserà nei secoli, sopravvivendo perfino ai bombardamenti della Seconda guerra mondiale.

About Mainz Cathedral

Mainz Cathedral (Hoher Dom St. Martin) was ordered built by Archbishop Willigis in 975-976 in the Ottonian architectural style, modelled explicitly on St. Peter’s in Rome and designed with a transept and dual choirs to reflect the archbishopric’s imperial stature. On 29 August 1009, the very day of its consecration, the cathedral suffered extensive fire damage; reconstruction under Archbishop Bardo took nearly three decades, with the main portions complete and the building usable again by 1036. A second major fire in 1081 required further rebuilding, with Emperor Henry IV supporting reconstruction efforts from around 1100. Gothic belfries were added to the crossing towers in 1361 (east) and 1418 (west), each topped with a pyramid roof, and the building today combines its original Romanesque core with later Gothic chapels and towers and Baroque roof elements. The cathedral burned a total of seven times across the centuries, was rebuilt after each, and survived even the bombing raids of World War II. Since the Middle Ages, the Archbishop of Mainz held the right to crown German kings and queens, and the cathedral hosted the coronations of seven German kings. It now holds the tombs and funerary monuments of numerous former Electoral prince-archbishops, and the printer Johannes Gutenberg — a native of Mainz — is buried here alongside Archbishop Bardo, who oversaw the cathedral’s first reconstruction.

Key facts

  • Foundation: ordered by Archbishop Willigis, 975-976, modelled on St. Peter’s in Rome
  • 1009 fire: destroyed the cathedral on the very day of its consecration, 29 August 1009; rebuilt under Archbishop Bardo, usable again by 1036
  • 1081 fire: required further reconstruction, supported by Emperor Henry IV from c. 1100
  • Gothic towers: belfries added 1361 (east crossing tower) and 1418 (west crossing tower), pyramid roofs
  • Seven fires total: across the centuries, each followed by reconstruction; survived WWII bombing
  • Archbishop-electors: held the right to crown German kings and queens; seven royal coronations held here
  • Notable burials: Johannes Gutenberg and Archbishop Bardo, among numerous Electoral prince-archbishops

History

Archbishop Willigis’s explicit modelling of his new cathedral on St. Peter’s in Rome reflects Mainz’s genuinely exceptional status within the medieval Holy Roman Empire: as one of the empire’s most senior ecclesiastical princes and, from the mid-14th century Golden Bull onward, formally the presiding Archbishop-Elector among the seven electors who chose the German king, the Archbishop of Mainz required a cathedral whose scale and prestige matched an office with genuine imperial-level authority — a status the building’s repeated, determined reconstruction after seven separate fires across the centuries only reinforces, since each rebuilding represented a conscious institutional refusal to let the see’s premier church remain diminished.

The cathedral’s role hosting seven German royal coronations situates Mainz directly within the empire’s core constitutional machinery, the Archbishop of Mainz’s coronation privilege giving the city a formal, recurring role in the transfer of royal power comparable to few other German ecclesiastical seats. Johannes Gutenberg’s burial within the cathedral connects the building to one of the most consequential technological developments in world history — movable-type printing, invented in Mainz itself in the 1440s — giving the cathedral a further layer of significance entirely independent of its ecclesiastical and dynastic history.

What you see

The cathedral’s layered combination of Romanesque core, Gothic chapels and crossing towers (1361 and 1418), and later Baroque roof elements offers a legible thousand-year architectural record surviving seven separate fires. The tombs and funerary monuments of the Electoral prince-archbishops, concentrated within the cathedral, give visitors a dense record of Mainz’s medieval and early modern ecclesiastical-political elite. Johannes Gutenberg’s tomb adds a further specific point of interest connecting the building to the invention of European printing.
