Postojna Cave

A fantastic web of tunnels, passages, galleries and halls, the 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, which has already reached 38 million in 200 years.

Five-metre jewel

Postojna Cave's most beautiful stalagmite is called the Brilliant. Looking at this marvellous shiny white limestone formation, you cannot but agree that it is entirely worthy of its name. The approximately 5-metre-tall stalagmite 'Brilliant' is located at a spot with a strong and even drip from the ceiling. A thin layer of pure calcite sinter is deposited constantly and evenly by the water trickling down the rounded crown of the stalagmite, which gives the stalagmite an outstandingly white and shiny appearance. It therefore comes as no surprise that the stalagmite has been the symbol of Postojna Cave and the Slovenian Karst for decades. Standing right next to it is a baroque-like pillar.

Postojna Cave is without doubt one of the most diverse cave systems in the world. Its 24 kilometres of passages, galleries and magnificent halls offer a unique experience of the underground world.

The olm (Proteus anguinus) has always excited people's imagination. Initially, it was believed it was the dragon's offspring brought onto the surface by high waters. As a matter of fact, there might be some truth to these old beliefs. The olm is a neotenic animal, which means that adult olms retain most of their juvenile features. And if the olm decided to grow up… wouldn't it perhaps really turn into a dragon?

Around the Cave on board a Train

The Postojna Cave train has been taking visitors around the cave for 140 years. Its 3.7-kilometre long journey begins at the train-boarding platform of the unique cave railway, where – especially in the summer – a lot of hustle and bustle is present, the kind that is otherwise typical of the world's largest railway stations. In 1818, just over 300 metres were accessible, whereas today visitors get to enjoy more than 5 kilometres of show cave passages during regular cave tours lasting an hour and a half. 

For many years, visitors were able to explore the cave only on foot. In the spring of 1857, when the cave was visited by the imperial couple, three velvet sedan chairs were made for Empress Elisabeth and her ladies-in-waiting. In 1872, the tracks were laid all the way to the Great mountain (at the time known as the Calvary), giving visitors the option of a ride in two-seater carriages, which were pushed by the cave guides. Although the idea of introducing machines instead of man-power was present even prior to World War1, it was not realised until 1924, while the year before the entire railway system inside the cave was overhauled.

In 1928, a new administration building was constructed at the entrance to Postojna Cave, namely the present-day Jamski Dvorec Mansion, which housed a restaurant, a new railway boarding stop, and a visitor reception area. Here, visitors who chose to see the cave aboard the train would get on, while visitors who opted for exploring the cave on foot used the main entrance.

In 1957, to mark the formal opening of a new tourist season, the gasoline-powered locomotives, whose exhaust fumes reduced visibility in the cave, were replaced by battery-powered ones. However, with the ever-increasing numbers of visitors, the pre-war single-track railway, with a mere two passing sidings along the entire line, which only three locomotives could run on simultaneously, was becoming a real bottleneck.

The first engine-powered locomotive, Montania No. 803, is nowadays kept at the Notranjska Museum, while the second locomotive, Montania S-10, No. 2004, is on display in the square in front of the cave entrance.

On 20 June 1964, the official opening of the double-track train line took place; the line featured a loop near the cave entrance, while four years later, the second stage was completed with the construction of a loop all the way to the Concert Hall. Even today, the double-track loop line still allows uniterrupted transport of large numbers of visitors who visit the cave every year.

A Must-See Attraction

Throughout its 200-year history as a show cave, Postojna Cave has been visited by over 38 million enthralled visitors from all over the world, many of whom have left their signatures and comments in memory-filled visitor books.

One of Postojna Cave's notable features are without doubt the entries found in visitor books, especially in the so-called Golden Book of Visitors, which features numerous interesting names from the world's history, culture, science, politics, economy etc. Even back in the mid-19th century, Postojna Cave boasted numerous visitors not only from Europe, but also from Australia, China, India, and even Java and Sumatra.

Back in the day, visitors would sign their names directly onto the cave walls and even speleothems. Thus, the Passage of Old Signatures features signatures dating as far back as the 13th century, with most of them being from the 16th and 17th centuries.

The first 'official' visitor to the cave, which was at the time already set up as a show cave, was the Austrian heir to the throne, Ferdinand I, who was also the first to sign the visitor book. By 1941, the number of books amounted to 31, all of which are kept at the cave museum. In 1857, a special book was introduced, the so-called Golden Book of Visitors, used only for the signatures of the most eminent visitors. At present, the fourth volume is in use, and the visitor book entries speak volumes about the past times and the global political situation.

The long lists of signatures include the signatures by numerous eminent guests, including almost all European leaders, from Sweden to Greece, in particular the leaders of the countries which Slovenia used to be part of in different periods throughout history, as well as potentates from China and Japan, the Emperor of Brazil etc. To mention a few of them: Emperor Franz I (he visited the cave twice, in 1816 and 1818) and heir to the throne Archduke Ferdinand (1819); Napoleon's widow, Empress Marie Louise (1830 and 1832); heir to the throne Maximilian of Bavaria, the later king Maximilian II of Bavaria(1835); Archduke John of Austria (1837 and 1844); Emperor Franz Joseph I (1857 and 1883); Emperor Dom Pedro II of Brazil with Empress Theresa Christina (1871); King of Serbia, Milan Obrenović (1887 and 1888); Prince of Japan, Takehito-Shinnou, and his wife, Princess Yasuko, who could not resist the magical beauty of Postojna Cave - they visited the cave as part of their European trip in December 1889; King Carol I of Romania, and his wife, Queen Elisabeth (known under the pseudonym Carmen Sylva); King Victor Emmanuel III of Italy (1919 and 1922); Shri Vijayadevjy Mohandjevi, Maharaja of Dharampur, and his wife (1924); Benito Mussolini (1938).

The Yugoslav statesmen, President Josip Broz Tito, first visited the cave on 28 May 1945, and in the years after again on numerous occasions with different national delegations. In 1954, Tito hosted the President of Turkey, Bayar, and a year later, King Paul of Greece and his wife Frederica. The president of Egypt, Gamal Abdel Nasser, visited the cave in 1956 alongside Boris Kraigher, the then Chairman of the Executive Committee of Slovenia. In 1960, the cave was visited by the Egyptian president, Anvar El Sadat, and the Prime Minister of Sri Lanka, Sirimavo Bandaranaike. On 29 August 1963, Russian president, Nikita Khrushchev, and his wife Nina were accompanied by president Tito and his wife Jovanka.

Milan Kučan, the first Slovenian president, together with his wife Štefka, hosted a number of eminent guests of the modern era. On 12 October 2001, he visited the cave together with Queen Margrethe II of Denmark and her husband, Prince Henrik. That same year, the Postojna Cave's Golden Book of Visitors was signed by Princess Nori (Sayako) of Japan, the only daughter of the Japanese imperial couple. 2005 was the year of many presidential visits – as many as four state presidents visited the cave, namely the President of Poland, Wlodzimierz Cimoszewicz; the President of Slovakia, Dr. Ivan Gašparovič, with his wife Silvia; the President of Finland, Tarja Halonen, and the President of Armenia, Robert Kocharyan. Another eminent guest who visited the cave in 2005 was the Dutch meteorologist and the 1995 Nobel Prize Laureate in Chemistry, Paul Crutzen. In 2006, an invitation by Dr. Janez Drnovšek, President of Slovenia, was accepted by Albert II, Prince of Monaco, who visited the cave on 1 June. The Italian Prime Minister, Romano Prodi, was hosted in September 2007.

In recent years, Postojna Cave has likewise been visited by a number of eminent guests. In April 2013, the cave was visited by Borut Pahor, President of Slovenia, on the occasion of 800 years since the first known signature in Postojna Cave. A month later, Postojna Cave hosted the Speaker of Lok Sabha (Lower House of the Parliament of India), Meira Kumar, and the President of Estonia, Toomas Hendrik Ilves. In June 2013, the cave enthralled Their Imperial Highnesses, Prince and Princess Akishino of Japan, who were highly impressed by the splendours and magnificence of the subterranean world. They admired the nature and wondered how long it had taken for the tiny water droplets to create such a spectacular landscape. In the same year, Postojna Cave was visited by the US Senator of Slovene origin, Tom Harkin, and only a short time later, by three members of the Thai Royal Family, namely MC Bhansawali Kitiyakara, HRH Princess Soamsawali and HRH Princess Bajrakitiyabha. In 2014, Postojna Cave was honoured by a visit from the Nobel Laureate, Sir Harry Kroto, and his wife Margaret, a visit from Mr. Li Yong, Director General of UNIDO, and a visit from Mr. Sang-Hyun Song, President of the International Criminal Court.

In the middle of 2014, Postojna Cave hosted another eminent visitor, Slovenian writer Boris Pahor, who was - although he was just about to turn 101 - still full energy and creative zeal, and remembered that he had visited the cave for the first time when he was a student. Later that same year, in the autumn of 2014, we again hosted a number of special visitors, including the American astronaut of Slovenian-Indian origin, Sunita Williams, who commented that this had been a very special experience, and noted down in the visitor book that she was honoured to see the planet from above and below. The first eminent visitors of 2015 were hosted in January, namely a group of Russian cosmonauts from Russia's Star City Cosmonaut Training Centre, who were, during their visit to Slovenia, accompanied by Dragan Živadinov. The first presidential visit was hosted in February, when Postojna Cave was visited by the President of Malta, Marie-Louise Colerio Preca, who noted in the Golden Book of Visitors that "Nobody can describe the magical cave in Postojna. You must see to believe." In early spring 2015, Postojna Cave was visited by the First Lady of Turkey, Emine Erdoğan, during the ladies' part of an official visit to Slovenia, and a few days later, by one of China’s leaders, Sun Zhengcai, and a Chinese delegation, accompanied by the Ambassador of the People's Republic of China in Slovenia. Only a few days after Postojna Cave had celebrated an important milestone, i.e. welcomed the 36-millionth visitor, it hosted the Prime Minister of the Czech Republic, Bohuslav Sobotka, accompanied by his wife and colleagues. In June 2015, Slovenia's most popular attraction was visited by the new U.S. Ambassador to Slovenia, Brent Robert Hartley, and his wife, Elizabeth Dickinson.
