Postojna Cave has been attracting crowds of admirers from all over the world for over two hundred years. Today the known parts of the Postojna spelaean system comprise 24 km, which means that Postojna Cave is the largest show cave of the Classic Karst in Europe
Postojna Cave is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you get to meet this underground kingdom’s most famous inhabitant – the proteus (olm) – up close.
A fantastic web of tunnels, passages, galleries and halls, astonishing diversity of karst features, as well as easy access are certainly the main reasons for such popularity of the cave and a large number of visitors (more than 35 million of them in over 200 years).
A visit to Postojna Cave starts at the entrance station of the cave railway. The train first passes through an artificial tunnel, built when a double track railway was constructed (in 1964). The first natural tunnel is black and sooty, the consequence of a fuel dump explosion during the second world war. Next comes the Gothic Hall, richly decorated with stalactites and stalagmites, and the Ballroom, for 180 years a venue for events of various kinds. While you are viewing Nature’s sculptures, the train carries you for two more kilometres further into the cave, to the Great Mountain, where you alight and continue your visit on foot. The path leads past the Great Mountain (also known as Calvary), across the Russian Bridge into the Beautiful Caves, through Spaghetti, White and Red Halls, all the way to the Brilliant Passage, where the most famous stalagmite and symbol of Postojna Cave stands: the Brilliant. The route then leads past the aquarium containing human fish and into the Concert Hall, where you learn about the only underground post office in the world, buy some souvenirs, reboard the train and return to the surface.
Did you know that:
- the cave railway has existed since 1872 and electric lighting since 1883
- the oldest underground post office in the world has been here since 1899
- among 36 million visitors there were more than 150 state presidents, kings and emperors
From May to September, regular tours of the Postojna Cave take place every hour, while in the event of a high number of visitors, tours are organized every half an hour.
Groups are recommended to make advance bookings for all services in writing (firstname.lastname@example.org).
The Jamski dvorec Mansion was built in 1928 to the plans of the architect Pietro Palumbo.
The Mansion is actually the starting point of the cave – the famous sentence »Immensum ad antrum aditus« - Enter Traveller into this immensity - invites all visitors to enter the cave, to experience and explore it.
The size and the prominent exterior of the Jamski dvorec Mansion makes it an easily recognizable sight, while its position right next to the entrance to the Postojna Cave symbolically combines the interior of the cave and everything that is at visitors’ disposal outside.
Today the mansion is converted into a modern event centre. It is a perfect venue for a wide variety of exclusive business events, including seminars, conferences and state visits.
