Restoration and Experimentation on the Scaffolding of the Vandoni Spire


14 August 2017

The "gugliotti". Unusual spirals that climb up the sides of the Main Spire and nearly touch the feet of the Madonnina, crowning the Duomo and encircling the majestic “Great Spire ” in a marble embrace.

The Vandoni spire is the second of the "gugliotti" to be restored by the Veneranda Fabbrica, a continuation of the work begun by engineer Carlo Ferrari da Passano in the 1960s.

As of today, the surveys conducted have not revealed any particular structural issues, therefore restoration works are proceeding with normal maintenance.

The work will include replacement of damaged parts that can non longer reliably stand the test of time, with new elements.

Veneranda Fabbrica del Duomo di Milano

The restoration of these pieces will take place in the marble workshop, where skilled stonemasons transform stone into works of art.

The Vandoni Spire, located in the north-west, was completed in 1892 and gets its name from Giuseppe Vandoni, architect and head of the Fabbrica in the second half of the 19th century.

Furthermore, with this restoration the Fabbrica is testing a new kind of pre-consolidant material. Through the treatment and monitoring, both now and in the future, of the surfaces, the Fabbrica will be evaluating the product's ability to penetrate the structure and interact with it, in order to more effectively affix new materials.
