Yes, it exists. Literally. It's located a few kilometers from the city of Parma in the Emilia-Romagna region of Italy. A good plan is to get up early so you'll have time to see the entire process required to make the authentic Parmesan cheese, or as they say in Italy, Parmigiano-Reggiano.
The factory is made up of different halls, each with a different function. The most interesting of all is the Sala di Stagionatura where hundreds and hundreds of cheeses and stacked along high corridors to age. It's simply spectacular!
