The city of Florence took new measures on Tuesday to crack down on overtourism, just as the Italian government hosts the Group of Seven tourism ministers in the Renaissance city and seeks to significantly boost the country’s place as a top visitor destination.

Mayor Sara Funaro’s cabinet approved a 10-point plan that, among other things, would ban key boxes on buildings in Florence’s historic centre as well as the use there of loudspeakers by tour guides, a statement from City Hall said.

The keyboxes, small boxes with a digital pad that are used by owners of short-term rental apartments to easily leave keys for visitors, have become something of the symbol of local Florentine anger at tourists, whose numbers have rebounded after Covid-19.

In a recent protest, Florentines taped red Xs over the keyboxes, outraged at the transformation of the city centre and its magnificent palazzi and narrow streets into a collection of short-term holiday rentals that have displaced local residents and the long-standing businesses that served them.

According to national statistics bureau ISTAT, 2023 saw the most visitors to Italy with 134 million arrivals and 451 million people staying in hotels or other registered lodgings.

The number of visitors opting for non-hotel lodging grew nearly 17% compared with 2022, ISTAT said in a June report.

Italy ranks fourth on the UN World Tourism Barometer of international tourist destinations, after France, Spain and the United States.

The tourism industry contributed some 10.5% of Italy’s gross domestic product in 2023, according to Statista research.

Florence, long run by the centre-left, last year announced a ban on new short-term private rentals in the centre in hopes of stemming the exodus of locals.

It has repeatedly pressed for a special regulation from the national government, currently headed by prime minister Giorgia Meloni, to cap the number of days a property can be rented out at 120.

To date, only Venice has been permitted to limit short-term rentals. The lagoon city has been drowning under overtourism for years and this year began imposing a day-tripper tax to try to regulate tourist flows.

The right-left political divide over Florence and its tourism woes could come to a head precisely as Italy hosts the G7 tourism ministers starting on Wednesday in Florence.

At a warm-up event this weekend, tourism minister Daniela Santanche acknowledged some art cities were suffering from too many visitors.

But she said that overall Italy is hardly taking advantage of its tourism potential and needed 50 million visitors more a year.

Lamenting Italy’s fourth-place position on the list of the world’s top destinations, she said Italy needed to sustainably grow its tourism potential with quality offerings.

“We can grow much more, we can develop much more and the industry of tourism can truly become the leading industry of our nation,” she said.
