This cover from Slovakia depicts a 1,10 euro stamps issued in 2011, celebrating the
Dobsinska Ice Cave. This cave is a part of the UNESCO World Heritage Site "Caves of Aggtelek Karst and Slovak Karst". The site comprises 712 caves in Slovakia and Hungary. They represent a typical temperate-zone karstic system. The sediments and fossils in the caves show geological records of the subtropical and tropical climatic conditions from the Late Cretaceous and early Tertiary, as well as the Pleistocene glaciations. The original nomination in 1995 listed the Domica, Gombasecká, Jasovská, Krásnohorská, and Ochtinská caves on the Slovakian side, with
Dobšiná Ice Cave added as an extension in 2000. A modification of the site boundaries on the Hungarian side took place in 2008.
