A classic Margherita pizza stretching for more than 1.8 kilometers has been baked in Naples, setting a new Guinness World Record, a spokeswoman for the Neapolitan Pizza-makers Association said on Thursday.

The record-beating dish, measuring 1,853.88 metres, required 1.6 tonnes of tomatoes, 2 tonnes of mozzarella, 200 litres of olive oil and 30 kilograms of basil. It was prepared Wednesday by about 250 pizza-makers from Italy and abroad, spokeswoman Marta Canali said.

Slices were handed out to passers-by and to homeless people, as part of a publicity stunt for the campaign to have traditional pizza-making as practiced in Naples recognized as a UNESCO world heritage tradition.

Although pizza-like dishes have been around for centuries, Naples claims to be the birthplace of its modern version. According to tradition, the classic Margherita topping was invented there in 1889 to honour the visiting Queen Margherita (Margaret) of Italy.

A press officer for the Guiness World Records association confirmed that Wednesday’s pizza was the longest-ever pizza, beating the 1.6-kilometre example baked in June 2015 during the Milan EXPO world fair, which focused on food and nutrition
