Attractions
One of Slovenia’s major tourist attractions, Postojna Cave, is located near the town. Postojna Cave is the only place where you can see the most precious brilliant in the form of a cave formation and also meet the baby dragons. Just like the world above the surface, Postojna Cave boasts towering mountains, murmuring rivers and vast subterranean halls. It is a real challenge for explorers and the cradle of speleobiology.
The magnificent five-metre-tall bright-white stalagmite called Brilliant is a symbol of Postojna Cave and the Slovenian Karst. Standing next to it is an ornament-rich column.

Church
The parish church in the town is dedicated to Saint Stephen and belongs to the Koper Diocese. Within the urban area of Postojna, the church dedicated to the Prophet Daniel in the hamlet of Zalog and the chapel dedicated to Saint Lazarus at the town cemetery also belong to this parish.
