The stunning mine, carved entirely out of salt and containing over 2,000 different rooms, is on the UNESCO World Heritage Sites list and annually attracts over a million tourists from all over the world.
Nearly 1.86 million tourists visited the Wieliczka salt mine outside the southern Polish city of Krakow in 2019, up 7 percent on the previous year, the mine's president, Zbigniew Zarebski, has told PAP.
The treasure found at the Old Synagogue in Wieliczka includes a silver cup, five candlesticks, the parts for four or five brass chandeliers, and two silver-plated candlesticks – but mystery surrounds who put them there.
Over 1.7 million tourists from 200 countries visited the Wieliczka salt mine, outside the southern Polish city of Krakow in 2017, 200,000 more than in the previous year. "This is a historic record of attendance", Monika Szczepa from the mine told PAP.
