This may come as a complete surprise. I have found a building project I may never beat. The world’s largest salt mine!
Over 300 meters deep and 287 kilometres long. This place dates back to the 13th century.
We walked around for 2 hours and still saw less than 1% of the entire mine.
By the way, that chandelier is made out of salt. Omg
A 2 hour tour showed us 1%, so 8 photos and a few captions must be 0.000005% of this incredible place. There are many reasons to visit Krakow and it took me 3 visits to finally check the Salt mine out. Put it at the top of your list! Visitors info on the mine here
