Glassy waters mirror the belle-époque skyline of St. Moritz-Bad at dusk, while the snow-capped Piz della Margna (3,163 m) floats above the treeline in this atmospheric real-photo postcard — a scene that drew Europe's gilded class to the Engadin valley season after season. A small rowing boat rests on the near shore, a wooden fence recedes into shadow, and leafy branches frame the upper corners with the intimacy of a painter's vignette. The resort town's church tower and grand hotels are reflected perfectly in the still surface of Lake St. Moritz, capturing the tranquil interlude between the summer hiking season and the coming winter sports rush that would transform this valley into the cradle of modern alpine tourism.
