An Italian fishing village on the shores of Lake Como has imposed a fine of 200 euros ($228) on anyone caught strolling through its streets topless or wearing swimwear.

The decision is part of the latest measures aimed at curbing the effects of mass tourism in Italy.

Authorities in the village of Varenna have announced that wearing swimwear and going shirtless are only permitted on beaches, lakefront promenades, and boat docks.

The new rules, which came into force last month, also restrict the size of tour groups visiting the village to no more than 25 people.

Tour guides are also banned from using megaphones or any devices to amplify their voices.

Anyone violating these rules will face a fine of up to 400 euros ($456).

Gatherings of visitors have also been banned in a number of specific historic streets and alleys.

According to the village's official website, Varenna has become 'one of the most popular tourist destinations on Lake Como, thanks to its rich history, art, architecture and culture.'

The area is located about an hour north of Milan, and many films have been shot there, including 'Casino Royale' and 'Ocean's Twelve.' It is also a favorite destination for the wealthy and famous; American actor George Clooney owns a holiday home overlooking the lake.

Italian news channel TgCom24 surveyed villagers about the new rules. One unnamed resident said: 'You can do what you want, but when walking around or entering a shop, restaurant, church, or square, you must wear decent clothing.'

Another agreed, saying: 'It is not decent to walk around town half-naked.'

The ban is part of the latest series of measures aimed at regulating tourism in Italy.

Last month, authorities on the island of Sardinia banned the use of umbrellas on one of its most famous beaches due to safety concerns.

Many other Italian beaches have imposed time restrictions to avoid overcrowding, while cities such as Venice and Rome have introduced new taxes to limit tourism during peak periods.
