Russian bakers have produced an enormous blueberry pie in honour of the city of Krasnovishersk's 70th anniversary.

Chefs used hundreds of pounds of flour, berries and sugar, as well as 500 eggs to assemble the giant 300kg pastry.

"We started baking from seven in the morning, and we finished the first part - 50 pieces - at eight in the evening. Then some girls came after us at night and did some more," Svetlana Simonova said.

The pie, which measured 70 metres in length, might have taken over a day to bake, but only took a few minutes to eat.
