Save Venice's Long-standing Commitment to Safeguarding the Church of Santa Maria e San Donato

May 11, 2020

On the Island of Murano inside the church of Santa Maria and San Donato lies a 12th-century mosaic floor dating to the same period as that of the Basilica di San Marco. Measuring over 500 square meters (5380 square feet) the individual tesserae are made of porphyry, serpentine, and other precious Mediterranean stones. Christian iconographic themes are represented through figurative images of animals including a peacock, fox, eagle, and griffins, as well as symbolic geometric patterns.

This magnificent church is an extraordinary example of Save Venice’s longstanding dedication and commitment to preserving the artistic treasures of Venice. The organization’s concern for the fragile floor began in the 1970s with Save Venice’s first large-scale campaign, and continued with further maintenance and conservation from 2012 to 2015 and again in 2020 following the exceptional high tides in late 2019 that caused extensive damage. The church’s low elevation makes it particularly vulnerable to flooding and the precious mosaic floor was submerged in corrosive seawater on multiple occasions over the course of several weeks. You can see more of the damage in this clip from RAI TG VENETO news (In Italian).

During the 1970s campaign a watertight basin and subfloor was installed, but first the mosaics were cut into jigsaw puzzle-like sections that could be lifted and removed. Support was given to each section through the application of glue and cotton cloth, which became stiff when dry. These solid mosaic sections were coded and placed on specially constructed storage racks until they could be reinstalled.
Save Venice once again answered the call to action, allocating support for urgently needed conservation from the Immediate Response Fund launched in collaboration with the Italian Embassy in Washington’s “America Loves Venice” campaign. The Uni.S.Ve. conservation firm lead by architect Guido Jaccarino has teamed up with master mosaicist and conservator Giovanni Cucco to repair damaged and missing mosaic tesserae and mortar support in the central and right apses.  Sections of the left apse successfully treated in a 2012-2015 campaign withstood the tidal flooding, confirming that constant maintenance is the best preventative measure.  Holes and cracks in the walls where tidal water enters the church are being filled and repaired.  The rotting inner door and wooden entrance stairs were dismantled, revealing more mosaic floor that had not been visible for decades.

I am happy that Save Venice has taken our church to heart and considers our mosaic floor to be a priceless work of artistic heritage. The knowledge and experience that master Giovanni Cucco brings to this project is fundamental, and we are grateful to have such a fantastic team of conservators.” -Father Luca Biancafior

Save Venice’s dedication to safeguarding the church of Santa Maria e San Donato has lasted for nearly 50 years and was made possible thanks to the generous support of Mrs. Gladys Delmas (1970s campaign), The Thompson Family Foundation, Inc., Tina Walls, the James R. Dougherty, Jr. Foundation, Inc. through Beatrice Rossi-Landi, Trustee, Martha & Peter Weller (2012-2015 campaign), and the donors of the Immediate Response Fund (2020 campaign).
