The center of Venice, which welcomes millions of tourists every year, has a new look. After millennia of history - the first basilica was built in 826 – St. Mark's Square will be subjected to a series of important works. The aim is to defeat the high water, a phenomenon that afflicts “il salotto d’Europa” about 200 days a year. Work will begin in November when the safety of the Basilica will be completed through the installation of transparent gates, a sort of movable glass barrier. Then the start of the new Piazza San Marco. The project is entrusted to a grouping of 5 companies. Valves will be installed to prevent the passage of water. Satisfaction of local traders. “Finally new interventions against high water,” they say. However, Venice continues to lose inhabitants, for the first time now less than 50 thousand. The exodus of the residents is associated with the fact that the Venetians are getting older and older: the balance between newborns and deaths remains inexorably negative for years.
