TrollhÃ¤ttan was once a home to Saab, but as it goes in the postindustrial society production of tangible goods has shifted to cheaper parts of the world. Nowadays TrollhÃ¤ttan is a base to Swedish movie industry, which promptly earned the city the Trollywood nickname. The main attraction of the city is the system of channels, locks, waterfalls, floodgates and other contraptions I do not know names of. Set over the stunning rocky landscape, covered with moss and rust with running water everywhere, it is a truly stunning sight. All for an unknown purpose (at least to me). All this reminded me of Miyazaki’s Laputa, never mind the absence of rusty robots or flying castles. A unique place, well worth a visit.
