Gestalten's The Nature of Swimming explores the connection between people and water, along with the timeless pull that draws us back again and again to plunge into seas, lakes, rivers and springs. The book presents both naturally formed pools and human-made swimming spots set in rugged, breathtaking natural surroundings. This richly illustrated book also delves into the relationship between water and architecture, and the role that swimming and bathing in natural waters play in different parts of the world. The updated edition, released in 2026, features new locations in Germany, Austria and Switzerland.
