The Chocolate Museum is located in a historic building that already had a relationship with chocolate: in the 18th century the Bourbon army was a fanatical consumer of chocolate and, according to the ordinances, chocolate was present on the menus of the 18th-century military academies: “For breakfast each cadet and company officer shall be given one and a half ounces of chocolate with a quarter of a pound of bread...”. When the troops were in barracks, acting as garrison, chocolate was also commonly eaten. The halberdier corps, the monarch’s personal bodyguard, was enviously known as the “chocolateros”, because, as they were a pampered, elite corps, they consumed a great deal of chocolate.
