WHEN
It is believed to have taken place at the end of the 19th Century or the beginning of the 20th Century, in an alternate universe where flying technology was more advanced (a la Verne). According to Miyazaki, he wrote "Laputa" as a "science fiction novel which was written in the end of the 19th century
WHERE
In an imaginary country. The Slug Ravine, where Pazu lived was modeled after a mining town in Wales. Miyazaki went to Wales for location hunting, and learned that the town had had a huge labor dispute the year before. This story and the scenery of the depressed mining town (he being a former chairman of a union) affected him, and made him put the scene of the townfolk fighting with the pirates in the movie. You can also see a socialist-looking poster in the house of Pazu's boss.
