Ladakh has one of the most extreme climates known to mankind. It is cold and arid - with temperatures ranging from minus 30°C in winters to plus 30 °C in summers. Glacial melt is the only source of water here and many regions experience cold and dry howling winds periodically. Yet, the Ladakhis have not merely survived but thrived through indigenous wisdom and knowledge passed from one generation to another. Their architecture and building techniques are testimony to this.
