Opera della Cattedrale or Fabbrica del Duomo are two different ways of describing the same thing: a community at work to build and to take care of the symbol in which the ecclesiastical and civic community is mirrored and around which it prospers.
This magnificent church has been one huge unbroken building site since 1190, involving great artists, master craftsmen and highly skilled artisans working in constant synergy. The Construction Sites at Work have always been places of ceaseless study and work whose superb results continue to inspire awe and amazement in the visitor today.
From the foundation stone was laid all those centuries ago, the First Worker has always been the official directing our daily work and we are determined to maintain that tradition, lavishing our skills and our energy on every construction site in the Cathedral Complex.
