<P> Principal photography commenced on August 31, 1970, and ended on November 19, 1970 . The primary shooting location was Munich, Bavaria, West Germany, because it was significantly cheaper than filming in the United States and the setting was conducive to Wonka's factory; Stuart also liked the ambiguity and unfamiliarity of the location . External shots of the factory were filmed at the gasworks of Stadtwerke München (Emmy - Noether - Straße 10); the entrance and side buildings still exist . The exterior of Charlie Bucket's house, which was only a set constructed for the film, was filmed at Quellenstraße in Munich, Bavaria . Charlie's school was filmed at Katholisches Pfarramt St. Sylvester, Biedersteiner Straße 1 in Munich . Bill's Candy Shop was filmed at Lilienstraße, Munich . The closing sequence when the Wonkavator is flying above the factory is footage of Nördlingen in Bavaria . </P> <Ul> <Li> <P> Munich Gasworks as it appears today (building on the left) </P> </Li> <Li> <P> Munich Gasworks as it appears today </P> </Li> <Li> <P> Nördlingen, the town seen from above at the end of the film </P> </Li> </Ul> <Li> <P> Munich Gasworks as it appears today (building on the left) </P> </Li> <P> Munich Gasworks as it appears today (building on the left) </P>
