Grūtas Park (unofficially known as Stalin's World; Lithuanian: Grūto parkas) is a sculpture garden of Soviet-era statues and an exposition of other Soviet ideological relics from the times of the Lithuanian SSR. Founded in 2001 by entrepreneur Viliumas Malinauskas, the park is located near Druskininkai, about 130 kilometres (81 mi) southwest of Vilnius, Lithuania.
After Lithuania regained its independence in 1990, various Soviet statues were taken down and dumped in different places. Malinauskas requested the Lithuanian authorities to grant him the possession of the sculptures, so that he could build a privately financed museum. This Soviet-theme park was created in the wetlands of the Dzūkija National Park. Many of its features are re-creations of Soviet Gulag prison camps: wooden paths, guard towers, and barbed-wire fences.
Its establishment faced some fierce opposition, and its existence is still controversial. Some ideas originally meant to be a part of the park were never allowed. Examples include transporting the visitors in a Gulag-style train. Grūtas Park and its founder Malinauskas won the 2001 Ig Nobel Peace Prize (see List of Ig Nobel Prize winners#2001). Since January 2007 the park has been in dispute with the Lithuanian copyright protection agency. The agency requires royalties to be paid to seven Lithuanian artists who created some of the statues.
The park also contains playgrounds, a mini-zoo and cafes, all containing relics of the Soviet era. On special occasions actors stage re-enactments of various Soviet-sponsored festivals.
The exposition, consisting of 86 statues by 46 different sculptors, is organized into spheres. Each of the statues features a Soviet or socialist activist, many of them ethnic Lithuanians. The Totalitarian Sphere features sculptures of the main Communist leaders and thinkers, including Vladimir Lenin, Joseph Stalin, and Karl Marx. The Terror Sphere is dedicated to sculptures of founders of the Communist Party of Lithuania (Zigmas Aleksa-Angarietis, Vincas Mickevičius-Kapsukas) and officers of the Red Army (Feliksas Baltušis-Žemaitis, Ieronim Uborevich). It also has a sculpture of Felix Dzerzhinsky, the organizer of the Red Terror.
The Soviet Sphere includes sculptures of the four leaders of Lithuanian Communists, executed in the aftermath of the 1926 Lithuanian coup d'état, and activists of the Lithuanian–Soviet War of 1918–1919. The Red Sphere is dedicated to Soviet partisans, including Marytė Melnikaitė. The Occupation and Death Spheres showcase the brutal side the Soviet regime: mass deportations, suppression of the Lithuanian partisans, etc.
All 20 hectares of the park area is reminiscent of severe Siberia conditions with its guard towers, fragments of concentration camps and other Soviet elements plentiful all over the place.
Grutas Park has its annual event – a “Soviet” celebration.
