In the birthplace of pizza, the city of Naples in Italy, chefs have created the world's longest pizza - a pie two kilometres long that required 100 ambitious chefs to make.

The pizza was a traditional Margherita, with tomato sauce, mozzarella cheese and basil, and stretched across the Naples seafront. 

Chefs used 2,000 kg of flour, 2,000 kg of mozzarella, 1,600 kg of tomatoes, 30 kg of basil, 200 litres of oil and 1500 litres of water to make it.

A custom-made motorized wood-burning oven was built to bake the pizza, and it took 11 hours of work for the Naples chefs to complete the job. 

Their effort was enough to break Guinness world record for the longest pizza in the world. The previous record was set in Milan last year, with a 1,595 meter long pizza.

The organizer of the record-breaking event, Alessandro Marinacci, wants the title of the longest pizza to stay in Naples.

“It’s absolutely a point of pride for our city, which is the home of the pizza,” he told The Local.
