Barry Callebaut operates 66 factories around the globe, including the world's biggest chocolate-making facility in Wieze, Belgium.
While it isn't staffed by Oompa-Loompas, we imagine Willy Wonka would still be bowled over by the factory. It employs 900 people and, according to the company, produces "1,000 tonnes of chocolate every day and give or take a few days, 350,000 tonnes of chocolate a year."
The site is also also home to the firm's flagship Chocolate Academy, and features a chocolate bar and library, a chocolate-tasting "ritual room", and its very own 100-seat "Chocotorium" lecture theatre.
In February, it was announced that Barry Callebaut was planning to cut around 2,500 jobs from its global workforce, despite reporting a profit rise of 20% in the last financial year.
