When you think theme park, you think roller coasters and family fun -- gas masks or watching a reenactment of the crucifixion? Not so much. But then you haven't checked out some of most unusual theme parks in the world yet.
Stalin’s World
One of the most popular tourist spots in Lithuania, (where is it?) the official name is Grutas Park, and it’s divided into two zones: totalitarian and the zone of terror. Intended to be educational for the whole family (it does include a zoo and kid’s park), the fact that it’s surrounded by barbed wire might add a bit of a chill. Stalin's World is one of the most popular tourist spots in Lithuania.
Shijingshan Amusement Park
When your tagline is as blatant as this, it’s no wonder Shijingshan Amusement Park has been called a copycat of Disneyland. Though there was talk of copyright infringement, a similar park will open in Shanghai. Look at the photos and judge for yourself. Maybe it’s the second happiest place on Earth? 
BonBon-Land
Opened in 1992 near this city in Denmark, BonBon-Land was named for a candy factory. That doesn’t immediately explain why most of the rides are rather scatologicaly themed (like its roller coaster), and include unconventional characters like a vomiting rat. Yuck!
Gatorland
Opened in 1949, this family owned Florida institution is all about alligators. Known for its gator wrestling, a selection albino alligators, and the title of "Alligator Capital of the World," Gatorland bills itself as a place for the whole family to experience these giant reptiles.
Diggerland
What most see as construction equipment, folks in the UK see as amusement park material. With four locations, Diggerland is popular and all the rides are made out of real construction machines. You will get dirty! 
The Holy Land Experience
The Holy Land Experience in Orlando has attractions that suit its name. You can dine with Jesus and his disciples at a portrayal of The Last Supper, watch a reenactment of the crucifixion and take a ride on the Jesus Boat.
Suoi Tien Park
A Buddhist theme park? Why not? Located in this city, Suoi Tien Park is an interesting mix of water rides, Buddhist iconography and attractions devoted to escaping the torments of hell to reach eternal life.
Beijing World Park
Forget Epcot – see the world at Beijing World Park. With more than 100 models of historic world monuments all in miniature, you won’t need to go anywhere else. 
Pedroland
Pedroland is a strangely tacky roadside theme park dedicated to stereotypical Mexican culture. And it’s not anywhere near Mexico (where is it?). Whether you take a ride in the Sombrero Tower or play a round at the Golf of Mexico (really), you’ll feel very far north of the border. 
Dickens World
Not be confused with a more highbrow museum in London, this theme park attempts to make 19th century London fun for everyone. Meet Oliver Twist, take the Great Expectations Boat Ride – Victorian charm without the squalor, disease, and rats! 
Tierra Santa
In Argentina’s version of the Holy Land Experience, you can watch an animatronic Jesus rise from the dead every 30 minutes – and He's 40-feet tall. Located in this city, Tierra Santa makes for quite a pilgrimage. 
Crocosaurus Cove
Located near this famous attraction, Crocosaurus Cove is known for the Cage of Death, where visitors come face to face with giant saltwater crocodiles. Good for years of nightmares for the kids.
Dwarf Empire
This is not your grandparents' Munchkin Land. Located in this city, this extremely popular attraction provides a good salary and free room and board to its resident performers.Source:Specials
