Caves and castles in the Karst

Postojna is barely on of the 20 largest towns in Slovenia, but arguably none are more well-known throughout that world (including the capital Ljubljana) than this relatively nondescript settlement in the southwest of the country that wasn’t even officially recognize until 1909. The reason is amazing network of karst caves that lie just below its surface. First opened to the public in 1819, the world-famous Postojna Cave is said to have attracted more than 35 milion visitors over the past two centuries.
