The hilltop fort at Pula, a Venetian construction to guard against Ottoman attacks, dominates the town and bay of this pretty Istrian port. Using stone plundered from the adjacent Roman theatre and built on the site of earlier forts the structure underwent continual improvement and remained in use until the end of World War Two.


Visiting Pula Venetian Fort
The easiest way to visit the fort is just to walk there. There is no parking nearby (I think the nearest is about 200m away) and the streets are narrow and crowded. From the amphitheatre it’s less than 10 minutes walk and from the marina or historic centre it’s probably 5 minutes.
Tickets can be bought at the entrance and include access to the museum and Zerostrasse tunnels. I think entry was €7 for adults. Allow a couple of hours if visiting the museum and tunnels too and maybe a bit more if you want to do a circuit outside the walls and look at the Roman theatre.
My Experience
Our visit here was as part of a larger road trip through Slovenia, Crotia, Italy and San Marino, detailed in my blog here. The Historical and Maritime Museum of Istria was a fantastic exhibition inside the fort, showing how the whole area around Pula was fortified between 1813 and 1918 with 200 forts, towers and defensive buildings as well as three lines of defence that included trenches, minefields and wire. Probably because of this the town was not seriously threatened in WW1 but as the Austrians were on the losing side they had to give it up anyway. The coastline is still littered with these forts, some of which are as impressive as those of Verdun. The living conditions for the soldiers in these forts was pretty dire with dirt floors, intermittent lighting, poor air and bad sanitation.
There was also an apothecary exhibition, showing the medicines at the turn of the 20th century and the process involved in creating them. The fort itself was a classic star fort design with a deep moat all round. The views were as impressive as you’d expect and there was also the entrance to the underground tunnels, both those of the early 20th century fort and the excavations to be used as air raid shelters built up until WW2. The tunnels could hold almost 50,000 people if needed, the entire population of the town.
I climbed the observation tower to look at the views and also did a walk around the outside of the fort. There is also a path down to the Roman theatre which i didn’t take. It looked like a modern area with raised seating constructed but I should have investigated further.

History
The Pula Fortress Kastel, a gem among Pula forts, has a history deeply intertwined with the city’s evolution. Constructed during Venetian rule in the 17th century, the fortress was initially built to guard against invasions.
Venice, recognizing Pula’s strategic maritime position, commissioned its construction. Over the years, the fortress underwent several modifications, especially during the Austro-Hungarian rule. These modifications strengthened its defences, ensuring that the city remained impregnable.
The purpose of the Pula Fortress Kastel was clear: it was a beacon of defence. However, as time passed, its role evolved, and it became a symbol of Pula’s resilience and a source of local pride.

That is an impressive fort! I like the pictures you took from different angles, really showing the depth of construction and the depth of the walls. Awful for the soldiers to live in such bad conditions. Do you have any more photos of the apothecary museum? I should think that was really interesting 🧐
