Success in Venice: “acqua alta” did not flood the basilica in pl. st. Mark

Success in Venice: “acqua alta” did not flood the basilica in pl. st. Mark

The debut of glass barriers came almost exactly three years after the record-breaking flood in Venice, which caused enormous losses, also inside the basilica. Water penetrated not only into the vestibule as it has always been, but also into the crypt. The mosaic on the floors and many valuable elements were damaged.

The barriers, which had not yet been inaugurated, stopped the water at the entrance on Sunday, where so far on such an occasion the water had poured in; even a hundred times a year.

In this way, the average tide was stopped, below a meter, in which the large Mose system of raised barriers is not activated, which prevents flooding of the city.

When it started working and its effectiveness was confirmed, the basilica remained a problem, which due to its location is exposed to regular flooding. Therefore, a team of engineers has developed a simple, ad hoc method of protecting it – installing transparent, reinforced barriers in front of the basilica.

Work on them comes to an end these days, but they have already stopped the water, which was considered a historic event in Venice. This protective strip spectacularly divided Saint Mark’s Square on the first Sunday in November: there was water everywhere and it was completely dry behind the barriers.

These panes are a temporary solution, waiting for the completion of more complicated engineering works, consisting in raising the entire surface in the area of ​​St. Mark’s Square. It will be an investment of EUR 50 million.

The installation of barriers that do not block the view of the basilica cost 3.5 million euros.
