Patrick Boyle, The Earl of Glasgow and his son David, Viscount Kelburn pose at their home Kelburn Castle on August 30, 2011 in Largs, Scotland. The Earl of Glasgow has asked Historic Scotland if the graffiti can remain as a permanent feature of the Castle. The local council allowed the mural to be painted on the wall by Brazilian artists in 2007, with a three year limit put on the graffiti pending the start of rendering work at the castle.(Photo by Jeff J Mitchell/Getty Images)

The Stone Forest or Shilin is a notable set of limestone formations located in Shilin Yi Autonomous County, Yunnan Province, People's Republic of China, near Shilin approximately 120 km (75 mi) from the provincial capital Kunming. The tall rocks seem to emanate from the ground in the manner of stalagmites, with many looking like petrified trees thereby creating the illusion of a forest made of stone. Since 2007, two parts of the site, the Naigu Stone Forest (乃古石林) and Suogeyi Village (所各邑村), have been UNESCO World Heritage Sites as part of the South China Karst.
