The Leaning Tower of Wanaka marks the entrance to Puzzling World, a unique amusement park in Wanaka. Since it was founded by Stuart Landsborough in 1973, the popular tourist attraction has added several optical illusions rooms, mind-boggling puzzles, gravity-defying sculptures and frustratingly-fun mazes. Many of the intricate exhibits were designed by Weta Workshop, the New Zealand special effects company who helped produce The Lord of the Rings Trilogy.
