About Zerostrasse Pula
Zerostrasse Pula is an underground system of tunnels and galleries beneath Kaštel, the central hill above Pula’s old town. The tunnels were developed before and during the First World War, when Pula was a major Austro-Hungarian naval port and needed shelters, communication routes and storage spaces beneath the city.
The accessible section at the foot of Kaštel has four entrances placed on different sides of the hill. These passages lead towards a central underground space, with the layout designed to keep air moving through the system. The tunnels are about 400 metres long, 3 to 6 metres wide and around 2.5 metres high, with a steady temperature of around 14–18°C.
Today, Zerostrasse is open as a visitor attraction connected with Kaštel fortress and the Historical and Maritime Museum of Istria. Visitors can walk through the cool corridors, see the scale of the shelter system and use the lift connection towards the fortress above.
Explore Zerostrasse Pula
Inside Zerostrasse Pula, visitors follow wide underground corridors that meet beneath Kaštel hill. The atmosphere is simple and powerful: concrete and rock walls, low fixed lighting, cool air and the sound of footsteps echoing through the passages.
Side chambers and alcoves show how the space could once function as a shelter and practical underground route. Some areas host temporary exhibitions, installations or displays connected with local history, while other parts remain more minimal, letting the structure itself tell the story.
One of the most useful features is the lift connection towards Kaštel. Many visitors start underground, then continue up to the fortress for city views, museum displays and a broader sense of Pula’s defensive history.

VisitPula Our Take
Zerostrasse Pula suits visitors who enjoy history, unusual spaces and short attractions that add something different to a city walk. It is especially good for families, couples and anyone exploring Pula’s Roman and Austro-Hungarian layers in one day.
The visit is worthwhile because it reveals a hidden part of the city rather than another above-ground monument. It works best in summer afternoons, when the cool tunnels offer a practical break from the heat, or as the first step before continuing up to Kaštel.
Allow around 30–60 minutes for the tunnels alone. The main limitation is that the underground section is relatively compact, so visitors expecting a very long tunnel route should combine it with the fortress and museum above.
