It's called Love Land. By the way, some of these photos are NSFW. Love Land is located on Jeju Island, an interesting little island just south of the mainland, which seems to have either a theme park or museum on the most obscure topics. Love Land is mainly a sculpture park. There are countless dirty sculptures, some in very impossible sex positions. It's a great way to spend a couple hours. Be sure to read the names of each of the pieces for even more of a laugh!
There were a few interactive crank toys like this one scattered throughout the park
Notice how the hills are boobs, and the penis in the background.
This section of female dominance was a bit weird...
The little details around the park made it even more awesome.
There is a whole exhibit of these little miniature sex scenes. All of them are super funny.
