Salina Turda, located in Turda, Romania, is home to an underground theme park that’s nestled inside one of the oldest salt mines in the world.
After excavations ceased in 1932, the salt mine, which dates as far back as the 17th century, served as everything from a cheese storage facility to a bomb bunker during World War II.
It has been turned into a fantastic underground theme park today.
When you visit, you’ll head down about 400-feet before reaching the submerged wonderland.
Once inside, you’ll find an amphitheater, a bowling alley, an underground lake with paddle and row boats, and even a Ferris wheel.
It’s easy to get distracted by the stunning rugged caverns, the result of mining that carved out over three billion tons of salt.
