The amazing underground structure of the Romanian "Salina Turda"
It is known that the place has been mentioned since the time of the Roman Empire, and today the "former salt cave" is operated as an amusement park.
It is unlikely that such large-scale structures, with walls 45 m high, were carved and polished with sticks, diggers and chisels.
