The park has been set up in close cooperation among the Municipality of Pivka, the Ministry of Defence, the curatorial department of the Military Museum of Slovenian Armed Forces and a number of enthusiasts and collectors from the area who contributed greatly both in terms of artefacts as well as knowledge.
The former barracks headquarters building is nowadays again serving a similar function with office spaces, a multimedia room, a museum shop and the Pivka Canteen, a canteen that offers an army-like ambient and the food to match (groups can even order dinners in the caverns based on menus from World War I). It also houses the exhibition called Regio Carsica Militaris, presenting the historical trajectories that have touched the area around Pivka since the Roman times onwards, with the occupying and transient armies leaving, among other things, a trail of forts and barricades.
An array of the bigger and more imposing artefacts is housed in the three big pavilions, with the newest one dedicated foremost to the Slovenian War of Independence and its historical context. Also on display are the equipment of the Slovenian Territorial Defence forces, the infamous Gazelle helicopter (associated with a very curious chapter of the war), tanks and other vehicles from the old Yugoslavian army, etc. Accompanied by additional explanatory materials, together they form the most comprehensive exhibition of this kind in Slovenia.
Other pieces include aeroplanes from around the world (among them the American F-86 Sabre and Yugoslavian SOKO 522), a Yugoslavian submarine P-9, quite a few tanks and an array of heavy artillery (like the famous German cannon Flak 88 and the American Long Tom 155mm cannon, both used during World War II). These pieces are presented not only as part of the industrial and technical heritage but are also accompanied by objects that offer a more personal historical perspective.
The park has also established two historical trails in the vicinity. The trails connect the old barracks in Pivka with an abandoned military polygon, an underground fort built by the Italians in the 1930s and its accompanying underground tunnels and other relevant points of interest.
Like the park, the annual festival of military history began in 2006. It has taken different forms, but its main components are still battle re-enactments, usually based on important historical moments. For example, to commemorate the 70th anniversary of the end of World War II in 2015, the battle for Berlin between the Red Army and the German Army was re-enacted.
The festival also features lectures, additional exhibitions, a flea market of military artefacts, children's workshops and other events.
