One of my most memorable experiences while visiting Poland was touring the Wieliczka Salt Mine in the town Krakow. This salt mine is now a historical site that displays several statutes, rooms, and chapels, all carved from salt; underground rivers; and a banquet hall reserved for weddings and religious events. I always found it fascinating that this salt mine has multiple functions. Not only does it provide Poland with the essential mineral that you can find on a dining room table, but it also serves an aesthetic purpose by inspiring creative forms of art and beauty.
