But can you remember when the city was the country's chocolate capital?
In 1886, Albert Jarman Caley opened Norwich's first chocolate company in Chapel Field East known as Fleur-de Lys works, in an effort to save the jobs of his workers who were making soft drinks, which at the time were sold seasonally, by giving them something to sell in the winter months.

By 1904 the factory was employing 700 people and chocolates were shipped all over the world, with 'Caley's Marching Chocolate' even being sent to British troops during the First World War.
Then in 1932, the company changed hands after being bought by John Mackintosh & Sons Limited for £138,000, and then five years later, Norwich gave birth to the first ever packet of 'Rolo'.
