Mathematician, physician, astronomer and engineer at the service of the Serenissima Republic of Venice, Bernardino Zendrini was a native of Saviore dell’Adamello. To him we owe the replacement, around 1738, of the weak banks of palafitte and stones, erected to protect the lagoon of Venice from high seas, with the famous "murazzi", barriers constructed along the shore between Pellestrina and the port of Chioggia with blocks of Istrian stone cemented with pozzolana mortar. A few years earlier, Zendrini had also been engaged in reclamation of the Viareggio area, dominated at the time by Lake Massaciuccoli, proposing in 1735 the construction of sluices with mobile gates which, by separating the freshwater coming from the lake from the salt water coming from the sea, managed in part to reclaim the surrounding area. The memory of these projects remains in his report All'illustrissimo Uficio della foce di Viareggio relazione, che concerne il miglioramento dell'aria e la riforma di quel porto, con una appendice intorno gli effetti delle macchie, per rapporto all'alterazione dell'aria [To the most illustrious Viareggio Harbour Entrance Bureau this report, which concerns the improvement of the air and the remodelling of that port, with an appendix on the effects of the maquis, with regard to alteration of the air] (1736).
