Located in the lowest area of Venice, the Piazza San Marco is known worldwide for its beauty. To keep the cathedral safe from flood damage, an architectural solution, using Pilkington glass, has been installed to provide enhanced protection to one that already exists. The steel and glass watertight barrier, will not only help protect the structure from erosion, but thanks to the choice of material, also provides unobstructed views over the square and Cathedral.

Pilkington Optiwhite extra-clear glass was chosen for this project, its low-iron content allows the true colour of the marble to be appreciated through the thickness of the glass barrier. The three-ply glazed panel is suitable for use in humid environments and capable of improving not only the mechanical characteristics, but also the post-breakage behaviour of the glazed panels. 

Matteo Grappiglia, Director of GR Strutture of Vigodarzere, the company that carried out this project: "On receipt of the order in March, the project was subjected to detailed engineering and design work, that included preparatory processes for the production of metal components in the workshop, culminating in sealing the glass and steel modules – the heaviest one weighing close to 1,800kg."

“Despite the complexities, we were able to ensure that the two-month installation period was completed in time to preserve the narthex from the first high tide of the season on 7 November.”
