Badab-e-Surt, Iran These beautiful travertine terraces in northern Iran are an incredible natural phenomenon that developed over thousands of years. Travertine is a type of limestone formed from the calcium deposit in flowing water, and in this case it's two hot springs with different mineral properties. The unusual reddish colour of the terraces is down to the high content of iron oxide in one of the springs. Iran is a kaleidoscope of colour. Head to the Naqsh-e Jahan Square in Esfahan to find endless bright tiles in one of the biggest squares on the planet. #info #EverythingsInfo
