Criterion (vii): Calcite-laden waters from hot springs, emerging from a cliff almost 200 metres high overlooking the plain, have created a visually stunning landscape at Pamukkale. These mineralized waters have generated a series of petrified waterfalls, stalactites and pools with step-like terraces, some of which are less than a meter in height while others are as high as six meters. Fresh deposits of calcium carbonate give these formations a dazzling white coating. The Turkish name Pamukkale, meaning “cotton castle”, is derived from this striking landscape.
