Kaštel Citadel Fortress: A Fortress, Views, and History Combined
We had already been exploring Zerostrasse, and the Kaštel Citadel felt like a natural continuation of our waddle. We entered the citadel directly from Zerostrasse. There’s an elevator that takes you up, but you can also explore it independently. From the top, the views of Pula are incredible, unlike anything else in the city. And although the amphitheater often overshadows it, the Kaštel Citadel is definitely worth adding to your itinerary.

Kaštel Fortress sits atop the hill overlooking Pula, and reaching it is easy whether you’re waddling or using public transport. From the city center, you can stroll up the streets that wind around the hill, enjoying views along the way. Walking from Pula city center usually takes about 10 to 15 minutes, depending on your pace and which route you take.

Our Waddle Through Kaštel Citadel
After cooling off at Zerostrasse, we took the elevator that leads directly up to the citadel. It was incredibly convenient, and we can’t recommend it enough. It was a beautiful, sunny day, which made us even more excited to explore Kaštel Citadel. As you reach the top, you’re immediately greeted not only by the sun but also by plenty of trees, providing shaded spots so you don’t have to worry about getting burned on hot summer days. Without wasting a moment, we started our exploration, eager to take in every corner of this historic fortress.
Once we were up (because even with the elevator, you still have to waddle up a small hill), we started exploring by waddling around a bit. Still, before soaking in the views, we headed straight for the main observation tower that rises above the fortress. Climbing up the tower is a must, from its top you get one of the best panoramic views of Pula, including the Roman amphitheater, the red‑tiled roofs, and the sparkling sea beyond. The fortress’s layout includes this taller tower above the walls and bastions, designed to give defenders a strategic vantage point in earlier times and, today, to give an unbeatable lookout. As soon as we reached the top, we were struck by how much of the city we could see; every direction felt like a postcard.
The tower is about 12–15 meters above the fortress walls. Getting to the top involves climbing a few stone stairs, which are easy for most visitors to manage, and the effort is well worth it for the panoramic views you’re rewarded with.
After exploring the tower, we waddled around the rest of Kaštel Citadel, soaking in even more panoramic views of Pula. The trees’ shaded areas made it easy to enjoy the fortress comfortably, even on a sunny day. We came across several historic cannons and information boards that tell the story of the citadel, which makes it a really nice complement to a visit to Zerostrasse.
How Much Time to Explore Kaštel Citadel
Exploring Kaštel Citadel doesn’t take too long, but it really depends on how much you want to soak in the views. We spent about 30 to 45 minutes, which felt just right for wandering the walls, climbing the tower, and taking in the scenery. If you like to sit, relax, and snap plenty of photos, you might want to budget a bit more time; the fortress has plenty of spots that make you want to linger a little longer.

Best Time to Visit Kaštel Citadel
The best time to visit is when the weather is sunny but not too hot, so you can enjoy the panoramic views without feeling overheated. Spring and early autumn are perfect for pleasant temperatures and fewer crowds, while summer gives you long, bright days but can get warm on the hill. Mornings are great if you want to beat the crowds, and late afternoons offer golden light over the city, perfect for photos and a relaxed stroll around the fortress. So once again, it depends on your preference, but in general, it is never overcrowded and pretty spacious.
