New rules banning the use of loudspeakers and limiting tour group sizes to 25 people have come into force in Venice.
Officials said the measures were taken to limit the impact of overtourism on the Italian city.
The canals of Venice’s historic district make the city one of the most visited places in Europe.
Venice introduced a daily entrance fee of €5 (£4) earlier this year, after initially banning cruise ships from docking during the 2021 season.
Overtourism is widely considered one of the most pressing problems in Venice, which has a population of about 250,000 and more than 13 million visitors in 2019.
Visitor numbers have since declined but are expected to exceed pre-pandemic levels in the coming years.
Local residents of Venice have fled amid fears that tourists might overwhelm the historic island city.
Osio, a civic association that tracks housing in the city, said in a recent update that the historic district has about 49,000 beds available for rent to tourists, which is more beds than available to residents.
The change in tourism rules comes after UNESCO experts warned last year that Venice could be placed on a list of World Heritage in Danger as the effects of climate change and mass tourism threaten to irreversibly change it.
The U.N. cultural agency ultimately did not include Venice in the list, recognizing attempts to address the island’s problems through flood protection systems and measures to reduce the impact of mass tourism.
