Base 20

Base 20 is one of Slovenia’s most important historical sites and a strong choice for visitors who want a place with a clear story, set in calm forest surroundings. In the heart of Kočevski Rog, it served as a secret headquarters of the Slovene National Liberation Movement from April 1943 to December 1944, and today it is protected as a monument of national significance.

Why go

What makes Base 20 stand out is that it remains preserved as a whole and is described by the museum as the only secretly built and preserved resistance headquarters of its kind in Europe. That gives the visit real weight: it is not just a walk through a historic site, but a chance to understand the wartime conditions that shaped it. Dolenjski muzej states that Base 20 is open to visitors year-round, while guided tours of the exhibitions and films are available from 1 April to 31 October between 8:00 and 16:00 by prior arrangement.

What to expect

The site is in the forest of Kočevski Rog, which adds to the sense of seclusion and explains why it remained hidden for so long. Parking is available in the sandy car park below Luke’s House. For groups, the museum asks for advance notice at least one week ahead; for individual visits, it is best to check arrangements directly with the museum before setting off.

Practical

Base 20 works well as a half-day outing or as part of a wider Dolenjska itinerary. Because this is a monument with guided access and seasonal time windows for tours, check the official website before you go for current hours, prices, and any updates.
