Historical landmarks in Croatia are even more captivating in 2025 with digital guides. From Diocletian’s Palace to Dubrovnik’s Walls — discover 11 must-see spots!

Are you ready to stroll through the history-scented streets of Croatia? In recent years, Croatia has become one of Europe’s most talked-about holiday destinations, enchanting visitors not only with its beaches but also with its cities steeped in history. In Split, you can start your day by having your coffee in the palace of a Roman emperor, and in the afternoon, stroll like a medieval knight along the walls of Dubrovnik. So, which of these historical treasures of the Adriatic would be your favorite? The breeze at Klis Fortress or the echoes of gladiator screams in the Pula Arena?

Those looking for a list of the historic buildings to see in Croatia are usually met with the usual suggestions, but in this article, we offer you not just postcards but a live time tunnel. These structures, each adorned with its own unique stories, help us understand not only the past but also the present. And yes, the only thing I thought when I first walked through Diocletian’s Palace was: “What would it feel like to live here?” The answer is simple: mesmerizing!

1. Diocletian’s Palace, Split

Where: In the center of Split, within walking distance from the harbor.

Diocletian’s Palace is at the top of the historic buildings to see in Croatia list for a reason: it is not only a historic relic but also a living city. When the Roman Emperor Diocletian retired in AD 305, he commissioned a palace by the seaside. But it wasn’t just any palace – it was practically a whole city. Today, within this colossal complex, you can find cafes, boutiques, art galleries… and even people live here! The answer to the question “What would it be like to live in a palace?” lies right here.

It is best to explore in the early hours of the morning during the summer months, since Split is notoriously hot and crowded. The best times to visit are late May and early September. The weather is lovely and prices are more reasonable. The cellars beneath the palace serve as a perfect escape during the summer heat. Moreover, in these cellars, there are small stalls where you can find everything from handmade goods to local wines.

If you find yourself here, stop by the Vestibule area and look up. The skylight opening in the center of the domed structure is an architectural marvel. If you happen to catch an a cappella group playing early in the morning, your ears will also be touched by history.

My favorite moment? I got my morning coffee and sat among the columns, accompanied by the sound of a violin. Perhaps that was the exact peace envisioned by the emperor. If you want culture, history, and a touch of local life to blend together, Diocletian’s Palace in Split is a true masterpiece for you.

2. Dubrovnik City Walls

Where: Dubrovnik, on the Dalmatian coast in southern Croatia.

One of the most iconic among the historic buildings to see in Croatia is undoubtedly the Dubrovnik City Walls. These magnificent walls, stretching over 2 kilometers, began to be built in the 10th century and have protected the city for centuries from pirates, invasions, and even, jokingly, from Game of Thrones fans (seriously, the crowds are quite something). In some places, the walls reach up to 25 meters in height, offering a breathtaking view of the Adriatic Sea.

Along the walkway, you can see towers, gates, and even ancient cannons and bastions. One of the most beautiful stops is the Minceta Tower, because it is the highest point in the city and guarantees Instagram-worthy photos. This was also the place where, in Game of Thrones, Daenerys searched for her lost dragons. Even for someone not interested in the series, the historical ambiance and panoramic view are enchanting.

As of 2025, the entrance fee is around 35 Euros for adults (yes, a bit pricey but definitely worth it). I recommend going early in the morning or near sunset; the light is better and there are fewer people. Be sure to bring water and, if you’re visiting in summer, be prepared with a hat and T-shirt. This walk isn’t just a casual “let’s check out the walls” – it’s a serious cardio workout!

When I first visited, I was quite unprepared. Climbing the walls under the sun, I felt part history buff, part half-marathon runner. Yet with every step, witnessing Dubrovnik’s multifaceted character and the endless blue of the sea from above, it was truly an unforgettable experience. If you’re open to history, vistas, and a bit of exercise, these walls will capture your heart.

3. Pula Arena

Where: Pula, in the southern part of the Istrian Peninsula, on the Adriatic coast.

Listed among the historic buildings to see in Croatia is the Pula Arena, one of Europe’s best-preserved ancient amphitheaters. Built in the 1st century AD with a capacity of 23,000, it is like the little brother of the Colosseum in Rome. But believe me, it’s less crowded and more intimate. As you wander here, you’re not just touching stones, but thousands of years of history. And yes, gladiator fights once took place in this arena!

In 2025, the annual Pula Film Festival held here in the summer is very popular. Watching a movie amid ancient stones? I think this experience is unmatched anywhere else. Moreover, in the summer evenings, the arena hosts classical music concerts and modern performances. These ancient stones are still a living stage: history by day, art by night… A wonderful combination, isn’t it?

The entrance fee is about 10 Euros for adults. I suggest visiting early in the morning or in the late afternoon when the light is softer and the shadows cast by the stone walls create perfect photo opportunities. Plus, taking a break in the shade during the summer heat is priceless. If you opt for a guided tour, you might even encounter guides in gladiator costumes – a bit theatrical but fun!

When I first went there, scenes from Hollywood movies ran through my mind, but then I sat quietly among the stones and watched my surroundings, and a completely different feeling overwhelmed me. Silence and history… Sometimes they convey more than a concert. If you’re interested in ancient Rome and want a blend of history and culture, the Pula Arena should definitely be on your itinerary.

4. St. James Cathedral, Šibenik

Where: In the center of Šibenik, very close to the sea, in the Stari Grad (Old Town) area.

Among the historic buildings to see in Croatia, the St. James Cathedral holds a special place, a masterpiece where Gothic and Renaissance architecture dance in harmony. This cathedral, inscribed on the UNESCO World Heritage List, was begun in 1431 and completed in 1505. It was built with such skill that every stone and arch seems handcrafted. Especially striking are the more than 70 different stone portraits on the exterior – yes, you read that right, facial expressions – both surprising and impressive.

The cathedral’s architect, Juraj Dalmatinac, worked the stones so artfully that it would be more fitting to call him a sculptor than an architect. Once you step inside, you’ll notice how soft the stone appears. Marble columns, reliefs, and barrel vaults transport you to another era. On summer days, the cool and calm interior offers a welcome respite from the bustling crowds outside.

As of 2025, a digital audio guide is available in some sections of the cathedral, and with an app that you can download on your phone, you can learn about every corner of the building. The entrance fee is about 5 Euros. I recommend visiting in the morning, as the cathedral tends to be crowded with cruise tourists in the afternoon. If you plan to take photos, the hours with soft light are a big advantage.

When I first entered, I couldn’t take my eyes off the mosaics on the ceiling. At that moment, I thought: How can a building so ancient feel so alive? Perhaps some places have the power to suspend time. If you seek history, art, and a bit of spiritual ambiance in your travels, the St. James Cathedral will leave an impression on your heart. This Gothic-Renaissance beauty is like a living gallery – take a look, then decide. The details on the exterior are so finely crafted that one can’t help but wonder, “How was such care possible back then?”

5. Old Town of Trogir

Where: 30 kilometers west of Split, on a small island off the Dalmatian coast.

The Old Town of Trogir, which adds an elegant touch to the list of historic buildings to see in Croatia, is one of the few places where you can still feel the medieval atmosphere. Although the town was established on a small island, it is connected by bridges to the mainland and to Čiovo Island. So it is both secluded and accessible – just like in your dreams. It is no coincidence that it is under UNESCO protection – while walking these streets, the distance to history is only a step away.

With its narrow cobblestone streets, paving stones, and corner towers that seem ready for a knight to appear at any moment, Trogir was once under Venetian influence. Thus, it is like an open-air museum where Gothic, Renaissance, and Baroque architectures merge. Particularly, the St. Lawrence Cathedral and its famous Radovan Gate offer a visual feast full of details. In 2025, the entrance fee to the cathedral is about 4 Euros, and the view of the town from the clock tower is truly breathtaking.

The charm of Trogir is not only in its stone buildings. The small restaurants lining the harbor, fresh seafood, and homemade ice cream also nourish the soul. I suggest visiting early in the morning when the crowds have not yet awakened, so you can see the true face of the town. In the late afternoon, the promenade along the harbor greets you with a romantic backdrop of a golden sunset.

When I was there, I lost all sense of time. With ice cream in one hand, my camera in the other, and a goofy smile on my face, I felt like a time traveler turned into a tourist from the Middle Ages. If you’re seeking history, aesthetics, and a bit of tranquility, the Old Town of Trogir will more than satisfy the traveler in you. This is the place where one might say, “This town is too beautiful not to be preserved.” Get lost in the cobbled streets and sip your coffee in the small squares. It’s as if time has stood still. If you have even a slight interest in architecture, you will fall in love with it.

6. Euphrasian Basilica, Poreč

Where: Poreč, on the west coast of the Istrian Peninsula, adjacent to the captivating blue waters of the Adriatic.

Among the historic buildings to see in Croatia is the Euphrasian Basilica, one of the most magnificent examples of Byzantine architecture. Constructed in the 6th century, this sacred structure has survived almost unchanged for centuries. Its inscription on the UNESCO World Heritage List in 1997 is no coincidence – the mosaics are still vibrant, and the details appear as if they were made yesterday.

Once inside, your eyes will inevitably be drawn to the golden mosaic in the apse. The depiction of the Virgin Mary, angels, and sacred figures are so elegantly rendered that the line between art and faith blurs. As of 2025, a small museum is also open inside the basilica, exhibiting various objects, inscriptions, and religious artifacts from the early Byzantine period. The entrance fee is around 6 Euros.

It makes the most sense to visit in the morning during the summer, as the basilica is quite small and fills up quickly. Guided tours are available, but sometimes it is enough to just sit quietly and admire the ceiling frescoes. Outside, the salty breeze from the Adriatic contrasts with the serene calm of the mosaics… This combination is truly soothing for the soul.

When I first stepped inside, I couldn’t take my eyes off the ceiling mosaics. In that moment, I thought: How can a building so ancient be so alive? Perhaps some places have the power to suspend time. If you are looking for both history and spirituality, the Euphrasian Basilica will deeply move you. The colors, details, and craftsmanship are simply enchanting. If you want to experience Byzantine aesthetics, it’s like an open-air museum.

7. Klis Fortress, Near Split

Where: Approximately 15 kilometers northeast of Split, on a high hill in the town of Klis.

Perhaps the most strategically located among the historic buildings to see in Croatia is the Klis Fortress. Like an eagle’s nest, it offers a 360-degree panoramic view that unveils Split and the Adriatic coast. Throughout history, this fortress was used by the Romans, Byzantines, Ottomans, and Habsburgs, and with its medieval stone walls and battle scars, it stands almost as a monument to history itself.

As of 2025, the entrance fee to the fortress is about 10 Euros. I recommend visiting early in the morning or in the late afternoon when the sun is softer. The walking path is more enjoyable then, and watching the sun set over Split makes you feel, “I’m really glad I came.” Inside the fortress, there is also a small museum displaying armor, maps, and period weapons. In the summer, there are even historical reenactments in costume – a bit theatrical but very entertaining.

For Game of Thrones fans, Klis Fortress was featured as the city of Meereen in the series. But believe me, this place is so much more than just a set piece. This fortress deserves a visit not only for its TV fame but also for the connection you establish with real history. The wind here always seems to whisper something… perhaps the tale of an ancient warrior or the dream of a fallen prince.

When I visited, the weather was a bit overcast, which only added a dramatic beauty to the scene. Standing atop the walls, gazing out over the Adriatic, the distance between me and history completely vanished. If you’re looking for a bit of adventure, breathtaking views, and plenty of history, the Klis Fortress is waiting for you. This fortress has witnessed much—not only in TV series but also throughout history. Standing atop it, you might just feel like a true “lord.”

8. Ston City Walls

Where: In the town of Ston, at the beginning of the Pelješac Peninsula, about 60 kilometers northwest of Dubrovnik.

Among the historic buildings to see in Croatia, the Ston City Walls occupy a unique position as one of Europe’s longest defensive walls. This stone serpent, 5.5 kilometers long, was built in the 14th century by the Republic of Dubrovnik to protect the salt pans and the strategic region. It still stands and remains impressive, and almost the entire wall is walkable.

When you start climbing the walls, you might find yourself a little out of breath, but the view from the top is well worth it. On one side, the shimmering Adriatic Sea; on the other, the geometrically pleasing salt pans… As of 2025, the entrance fee is about 10 Euros, and walking the entire length takes around 1.5 to 2 hours. Along the way, there are rest stops and informational panels. Choosing the right footwear is important; this is not just a city tour, but more like a nature hike.

While in Ston, don’t just settle for the walls. In the town, affordable restaurants and the famous Ston Mussels await you. Salt production continues to this day, and guided tours are offered for interested visitors. The nearby village of Mali Ston is also within walking distance and a bit quieter.

An elderly gentleman I encountered while walking the walls once told me, “These walls were worth more than salt.” And indeed, they are not just a defensive structure but also a symbol of economic, political, and cultural significance. If you’re seeking a varied, active experience with plenty of vistas, the Ston City Walls might tire you out but will ultimately reward you… One of Europe’s longest walls. As you hike, the view of the sea and salt pans accompanies you – a bonus leg workout!

9. Church of St. Donatus, Zadar

Where: In the center of Zadar, on Forum Square, surrounded by ancient Roman ruins.

One of the most striking among the historic buildings to see in Croatia is the Church of St. Donatus in Zadar. Built in the 9th century, this structure is one of the early examples of Romanesque architecture, and its circular form sets it apart from other churches. So much so that from the outside, it might resemble an ancient temple. Together with the adjacent Roman Forum, it forms the historic heart of Zadar.

The interior of the church is simple yet impressive. Its stone and brick walls and the almost unadorned interior lend it a mystical quality. The most notable feature is its acoustics. In 2025, the church continues to serve as a concert venue filled with classical music performances. If you visit in the summer, you might catch a free concert as part of the Zadar Music Evenings.

The entrance fee is around 5 Euros, and the visiting hours are generally from 9 AM to 7 PM. It is best to visit early in the morning, as the afternoons tend to be hot and crowded. Right next to the church, there is an open-air café; a coffee break against the backdrop of historic walls can be a delightful reward.

When I first stepped into the church, the resonating silence and the echo of my footsteps among the stone walls made me feel as if I were in direct contact with history. If you are looking for distinctive architectural forms, simple yet impressive structures, and a bit of an inner journey, the Church of St. Donatus in Zadar is definitely a must-visit. If you happen to catch a concert there, you’ll be amazed at how the sound echoes off the walls. The acoustics are as enchanting as the architecture.

10. Rector’s Palace, Dubrovnik

Where: In the Old Town of Dubrovnik, just off Stradun Street.

The Rector’s Palace, included among the historic buildings to see in Croatia, is an elegant fusion of Gothic, Renaissance, and Baroque architecture. Built in the 15th century as the residence of the Rector of the Dubrovnik Republic, it served as both an official state building and a private residence. The columns and arched entrance on the exterior offer just a glimpse of the details inside. Once you step in, you enter a time capsule of history.

As of 2025, the palace functions as the Dubrovnik History Museum, displaying period furniture, artworks, documents, and musical instruments. In one room, you might read ancient correspondence, and in another, experience a classical music performance. It is a quiet place that tells many stories. The entrance fee is approximately 15 Euros, and admission is free for Dubrovnik Card holders.

The palace’s courtyard is a serene retreat where you can cool off from the summer heat of Dubrovnik. Visiting in the early morning allows you to explore in peace and admire the interplay of colors on the stone walls in natural light. You might even encounter a couple taking wedding photos – because this palace is the epitome of elegance.

When I first entered, I completely lost track of time. Wandering through the silent corridors, it felt as if I were listening to the story of someone who once lived here. If you want to experience history not just from the outside but by walking through it, the Rector’s Palace will offer you just that. For those who wish to see it all under one roof… This palace was once the domain of the city administrators. Now it is open as a museum. The details, wall decorations, and furniture speak of history itself.

11. Trsat Fortress, Rijeka

Where: On a hill overlooking the center of Rijeka, in a strategic position facing the Adriatic.

Among the historic buildings to see in Croatia, the Trsat Fortress stands out not for its martial past, but for its tranquil atmosphere, impressive view, and historical character. Originally used as a defensive site during the Roman period, it was later converted into a medieval fortress. Today, it is a popular spot for both history enthusiasts and lovers of scenic views.

The interior of the fortress is small but meticulously maintained. Its walls and towers still stand proudly. Inside, there is a small art gallery and areas displaying artifacts from the period. As of 2025, admission is free, although various cultural events, concerts, and open-air theater performances are held during the summer. Visiting hours are from 9 AM to 8 PM – especially the climb at sunset is a visual feast.

There are two ways to reach the fortress: you can either walk up the stairs from the city center or drive up to the main road and then take a short walk to the fortress. If you set off in the morning, you can enjoy the cool air and explore without the crowds. The café inside the fortress offers affordable prices and a panoramic view of the Adriatic. Grab your coffee, sit by the stone wall, and take in the view of the city at your feet…

When I first climbed Trsat, it wasn’t so much the fortress’s history that moved me, but the stories the wind whispered. Sometimes the magic of a place comes not from its structure but from its silence. If you find yourself in Rijeka, the Trsat Fortress should definitely be on your list; because this fortress beautifies not only the past but also the present. Trsat Fortress overlooks Rijeka and always seems to flirt with the wind. Climb up, take in the view of the city… It’s hard to find a better place to end your day.
