Once it was ‘just’ a salt mine but now they turned the 120 meter deep Salina Salt mine into a subterranean History Musuem. A pretty cool tourist attraction, modernized with lots of activities like romantic boat rides in the underground, a mini golf track, bowling lanes and more.
It’s an magnificent sight and feels a bit like a journey to the center of the Earth. You can find the Salina turda salt mines’ in turda, Romania.
