Un’immagine curiosa rafigura il famoso gruppo scultoreo in Piazza San Marco nel 2019, durante la marea eccezionale. I Tetrarchi sembrano temere l’acqua alta: quasi metafora della minaccia che grava su Venezia e sul suo straordinario patrimonio culturale. Proprio per scongiurare il rischio di un affondamento deinitivo, dal 2019 la città ha completato l’implementazione di soluzioni come il MOSE, progettato per escludere le acque alte dal centro storico. Venezia oggi affonda, ahinoi. E in passato? Come hanno risposto i suoi abitanti nel tempo? L’archeologia documenta un crescente disallineamento tra i piani di calpestio storici e i livelli attuali di marea. In epoca antica, la sostenibilità si fondava su un adattamento continuo del costruito alle trasformazioni naturali del suolo, in un contesto segnato da eustatismo e subsidenza. Oggi, al contrario, un rigido paradigma conservativo ha bloccato ogni possibilità di evoluzione, trattando il “Bene Culturale Venezia” come un oggetto statico, imponendone la salvaguardia formale e cristallizzandone lo skyline. Il risultato è una trama urbana che ha smesso di crescere e di adattarsi al contesto ambientale. Ma è proprio nel dinamismo delle risposte storico-architettoniche che riconosciamo l’eccezionalità veneziana. Quando affermiamo di voler “salvare Venezia”, ci riferiamo alle sue pietre? O alla relazione profonda, fragile e straordinaria tra persone, laguna e architettura, che ne ha reso possibile l’esistenza?

Venezia affonda?

Abstract

A striking image captures the famous sculptural group in St. Mark’s Square during the exceptional high tide of 2019. The Tetrarchs appear to fear the rising waters - an almost metaphorical representation of the threat looming over Venice and its extraordinary cultural heritage. To avert the risk of permanent submersion, the city has since completed the implementation of the MOSE system, designed to keep high tides out of the historic center. Today, Venice is sinking - alas. But what about the past? How did its inhabitants respond over time? Archaeology documents a growing misalignment between historic ground levels and present-day tidal marks. In earlier times, sustainability was based on the continuous adaptation of the built environment to the natural transformations of the soil, shaped by both eustasy and subsidence. Today, by contrast, a rigid conservation paradigm has halted any evolution, treating the “Cultural Asset Venice” as a static object - preserving its formal integrity and freezing its skyline. The result is an urban fabric that has ceased to grow and to adapt to its environmental context. Yet it is precisely in the historical-architectural dynamism of its responses that we recognize Venice’s exceptional nature. When we say we want to “save Venice”, are we speaking of its stones? Or of the deep, fragile, and extraordinary relationship between people, the lagoon, and architecture that has made its very existence possible? The theme was chosen as a test case for scientiic communication to a non-specialist audience, to whom we wanted to illustrate the method that the archaeologists use to approach ancient literary sources in order to reconstruct evidence that no longer exists.
