The “Waterfall Castle in Poland” is one of those pictures. It features a stone castle seemingly carved out of the side of a lush cliff and gracefully caressed by gently falling water. Ancient yet immaculate. Manmade but also one with nature. The image appeals to our sense of adventure, our need to embrace history and our desire to be humbled by nature. So tantalizing close, yet almost impractically far for those who cannot afford to spend their vacation scouring the Polish countryside for this famed castle.
