There has always been a karst museum at Postojna, famed by cavers and other visitors, often closed for political reasons, then reopened, restructured, whatnot. If you went to Postojna during the Yugoslavia era, the museum was located beneath the tourist office at the town square. There were always others who had seen it, but it was always closed why I was there. Then it moved a few buildings up the road, where it was located for decades, but still always closed. At least there was now a sign at the door, and it is still marked in google maps at this location [2020]. But today the museum is reopened in a newly renovated building which is located further up the road and then right at the Hotel Sport.

Notranjska is an old Slovenian name for this area, the Austrians later called it Unterkrain (Lower Carniolia). This museum is dedicated to the area around Postojna, its people, its history, its culture, its geography and geology. So it is not a museum about the caves, its a local history museum. But as much of the local history is strongly related to a cave in one way or another, it actually is about caves. And there was Muzej krasa - Karst Museum, an exhibition about the cultural history of karst exploration. The exhibition once even had its own website, but its gone and only one of those annoying facebook pages remains. And there is an archive section on the museum webpage.

The museum will show you a lot of history about the Notranjska area. How people lived for centuries as farmers, how the country was owned by various foreigners until 1990. How it was at the frontier during two world wars and in between. Its departments are archaeology, biology, ethnological, history, conservation and restoration, and the pedagogical department. But it also has exhibits about caving and which clothes and equipment is needed, with a really impressive diorama of a caver. It explains how the karst struggles for its drinking water supply.

This museum is obviously the museum intended for the locals, not for the millions of tourists. As such it is free for citizens of Postojna and the main language in the museum is Slovenian. Nevertheless, it is worth a visit. And it uses modern technology, so install the NEXTO app and you will get a guided tour in Slovenian, English, or Italian. It offers in depth information, explanatory podcasts, and even additionally support for disabled.
