Tito's Bunker ARK D-0 Konjic — the complete visitor guide
Tito's Cold War Bunker (ARK D-0) Visit
What is ARK D-0, Tito's secret bunker near Konjic?
ARK D-0 (Atomsko Ratno Komandno Mjesto D-0) is a massive Cold War nuclear shelter built under Mount Zlatar near Konjic between 1953 and 1979 to house Yugoslav President Tito and up to 350 officials and military personnel in the event of nuclear war. Declassified in 1992, it is now open to visitors by guided tour only.
Beneath Mount Zlatar, 12 kilometres south of the town of Konjic, lies one of the most extraordinary Cold War relics in Europe. ARK D-0 — Atomsko Ratno Komandno Mjesto D-0, the “Atomic War Command Post D-0” — is a network of underground tunnels, apartments, conference rooms and technical facilities covering 6,500 square metres. It was built to shelter Yugoslav President Josip Broz Tito and up to 350 officials and military personnel during a nuclear war. It was operational for over three decades. Almost nobody knew it existed.
Today, ARK D-0 is one of the most unusual and compelling visitor experiences in the Balkans — a perfectly preserved time capsule of Titoist Yugoslavia, with its own power plant, water supply, decontamination showers, presidential bedroom and Politburo conference table. This guide covers the history, the visit itself, and how to plan a day around it.
The history of ARK D-0
Why Tito built it
Yugoslavia under Tito occupied a unique geopolitical position. After the Tito-Stalin split of 1948, Yugoslavia was the only communist country in Europe outside the Soviet sphere of influence — which meant it was a potential target for both NATO and the USSR. Tito’s government pursued a policy of non-alignment (founding the Non-Aligned Movement in 1961) but could not ignore the nuclear threat that hung over every European capital in the Cold War era.
Construction of ARK D-0 began in 1953, when Yugoslavia was at its most vulnerable geopolitically, and continued until 1979. The project consumed an estimated 4.6 billion US dollars (calculated at contemporary values) — a staggering investment for a small country, and one kept entirely secret from the Yugoslav public. Workers who built the facility signed lifelong non-disclosure agreements. External communications referred to the construction as a road-building project.
The bunker was designed to be self-sufficient for six months: it had its own water filtration from underground springs, diesel generators, air filtration and decontamination systems, food stores, and a communications centre with encrypted links to the Yugoslav military command structure.
The presidential apartments and political layout
The ARK D-0 complex has a clear political hierarchy embedded in its spatial layout. The most protected and finished spaces are the presidential apartments — Tito’s private bedroom, bathroom and office, furnished in the functional-luxury style of Yugoslav state socialism: solid wood furniture, parquet floors, a private telephone system. The conference room, where the Politburo would have met in the event of nuclear war, has its original table and chairs.
Senior officials had individual apartments of decreasing size and comfort as you move outward from the presidential core. Military and technical staff had dormitory-style accommodation. The hospital wing, communications centre and mechanical rooms are accessible on the tour.
Tito died in May 1980, one year after the bunker was completed. He never used it — though he did visit for an inspection. After his death, ARK D-0 was maintained by the Yugoslav military. The bunker was declassified in 1992 following the break-up of Yugoslavia, when it passed to the government of Bosnia and Herzegovina.

From Sarajevo: Tito’s Bunker and Konjic City TourCombining ARK D-0 with Konjic and the Neretva
Konjic town
Konjic town is worth an hour or two of your time. The Ottoman bridge (Stari Most) over the Neretva — not to be confused with the more famous bridge in Mostar — is a graceful seventeenth-century structure and the centrepiece of the town. The old bazaar area has traditional woodcarving workshops; Konjic is known throughout Bosnia for the quality of its carved wooden chests and furniture.
The town suffered significant damage during the 1992–1996 war and has been substantially rebuilt. The war-era history of Konjic and the surrounding Neretva canyon is documented in the local museum.
Neretva rafting
The stretch of the Neretva river between Konjic and Jablanica offers some of the best whitewater rafting in the Balkans — grade II–III rapids through a dramatic canyon, with the option to combine with a visit to the bunker in the same day. See our Neretva rafting guide for a full breakdown of the rafting experience, what grade of rapids to expect, and how to book.
Bosnia Explorer Tour: highlights of Mostar and Tito’s BunkerARK D-0 as art venue: the contemporary side
Since the bunker was declassified, it has also developed an unexpected second life as an art venue. The Sarajevo-based curator Edo Hozić initiated the use of the bunker for contemporary art exhibitions, and ARK D-0 has hosted major international exhibitions including works from documenta. The visual contrast between the Cold War infrastructure and contemporary art installations is extraordinary.
Check with the bunker management whether any exhibitions are scheduled during your visit — this adds a further dimension to the experience.
Practical tips
- Temperature: 10–12°C year-round. Bring a light jacket or fleece.
- Footwear: Comfortable walking shoes on uneven tunnel floors.
- Booking: Essential. Walk-ins are not always possible.
- Duration: 2–2.5 hours inside, plus travel time.
- Combined with: Neretva rafting, Konjic old town, day trip to Mostar (Konjic is roughly halfway between Sarajevo and Mostar).
- Mines: As with all rural areas in Bosnia outside well-marked sites, do not leave paths or enter unmarked terrain.
The Konjic day trip guide covers how to combine the bunker with rafting and the old bridge in a single day from Sarajevo. For those building a multi-day history itinerary, ARK D-0 is a key stop on the Bosnia war history itinerary.
ARK D-0 is unlike anything else in Bosnia — or anywhere else in Europe. It is meticulously preserved, historically profound, and extraordinarily good value. If you have one day to spare outside Sarajevo and want something genuinely different, this is it.
