As Venice tries to reduce the impact of mass tourism, the city has banned the opening of any more takeaway food outlets for the next three years.

It is an attempt to reduce the number of tourists snacking on church steps, historic bridges and canal banks, spoiling the aesthetics of what should be one of the most romantic and refined cities in the world.

Eating in the streets and piazzas of the World Heritage attraction also produces litter and encourages unwelcome flocks of pigeons and seagulls.

Large herring gulls have been known to snatch food out of people’s hands, as they do in some British seaside resorts.

The Venetian authorities are now saying “basta” (enough) to new pizza outlets, kebab shops and street food stalls.

The regulation was approved by Luigi Brugnaro, Venice’s mayor, on Wednesday.

It covers not only Venice but also the outlying islands of Murano and Burano, both of which are popular with visitors.

Murano is famed for its centuries-old tradition of glass blowing and does a thriving trade in selling hand-made ornaments, vases, bowls and even chandeliers.

Venice has struggled for years to impose a sense of decorum on its millions of visitors and takes a dim view of tourists holding impromptu picnics, jumping into canals and wandering around scantily-dressed during the summer.
