In the movie 'Willy Wonka and the Chocolate Factory'', in what country does Charlie and his family live? Where is the factory?

Principal photography commenced on August 31, 1970, and ended on November 19, 1970. After location scouting in Europe, including the Guinness brewery in Ireland and a real-life chocolate factory in Spain, production designer Harper Goff decided to house the factory sets and the massive Chocolate Room at Bavaria Studios. It was also significantly cheaper than filming in the United States, and the primary shooting locations in Munich, Bavaria, West Germany were conducive to the desired atmosphere for Wonka's factory. Stuart also liked the ambiguity and unfamiliarity of the location.
