under the dome
2009-2012

As with many churches in Italy, St. Stephen Martyr Cathedral in Pavia also had a troubled existence, characterized by numerous interruptions of construction with a succession and superimposition of structures in different eras that have caused structural weakening.
The construction began in 1488. Four Centuries later, in 1885, the dome (30 meters in diameter) and lantern were built. The cathedral wasn't completed until 1932. The structure of the dome, however, was not designed with proper attention, and since 1885 several structural instabilities have occurred. On March 17th 1989, the building was struck by the collapse of the nearby Civic Tower. Following that collapse, attention was focused on the supporting structures of the Cathedral. In 1995, after the results of structural health monitoring, it was decided to close the building to the public.
After the investigations necessary to design a static restoration and recovery, a massive steel frame shored with deep foundations was built, so as to ensure the support of the octagonal dome during the interventions of static consolidation.
In 2009 the works of restoration and structural consolidation of the tiburio, dome and lantern were completed. Once safety measures were undertaken, it was possible to remove the provisional metal shoring, to demolish even the footings of reinforced concrete foundation, and to proceed with other restoration projects, including removal of flooring, floor installation of radiant panels for heating system, realization of the concrete flooring plate, new electrical systems for liturgical functions and for the external lighting of the dome, as well as works of functional adaptation.
For over 17 years visitors and citizens were not able to enter the big hall of the cathedral (except for the celebration of the 2011 Christmas Eve) but now, after the December 2012 opening, they can once again walk under the dome.

I want to thank Studio Calvi for allowing me to take these photos inside the building site during the restoration works.
