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.
The salt mine, which dates as far back as the 17th century, was used for everything from a cheese storage center to a bomb shelter in WWII after excavations stopped in 1932.
Today, it has been transformed into an incredible underground theme park.
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.
Over three billion tonnes of salt were carved out by hand or machine and now the enormous void left behind has been converted into a giant underground theme park and spa. It even has its own boating lake that appears two minutes in.
And why wouldn’t you want to play mini-golf or receive a deep-tissue massage 400ft underground? It is when you realise they have managed to fit an entire Ferris wheel into the mine – around 2.40 minutes in – that you get some idea of how big it really is.
