Quick History of Trieste

To truly understand Trieste, you have to look beyond Italy’s borders. For centuries, this city wasn’t Italian at all – it was the Austro-Hungarian Empire’s only seaport. That history still lingers in the architecture, the languages you hear, and even what’s on your plate.

After World War I, Trieste became part of Italy, but it never shed its multicultural identity. Today, you’ll hear Slovenian on the streets, spot signs in multiple languages, and walk past a fascinating mix of Roman ruins and grand Austro-Hungarian buildings.

Food lovers, take note: Trieste’s cuisine is just as diverse as its history. Here, you can start your day with a buttery strudel, grab lunch with sauerkraut and pork, and end with a plate of fresh pasta – all without leaving the city center.

Trieste is also famous for its literary roots. The Irish writer James Joyce lived here for more than a decade, and the city still celebrates its bookish past with historic cafés where writers and artists once found inspiration. It’s the perfect place to slow down, people-watch, and imagine the centuries of stories that unfolded here.

1. Visit Castello di Miramare

• Hours: Castle is open 9 AM – 7 PM
• Cost: Museum is €15 for adults
  • Grounds are free to explore

If you’re looking for one of the most beautiful things to do in Trieste, make your way to Castello di Miramare, just a 15-minute ride from the city center. Perched on a rocky point with sweeping Adriatic views, this white-stone castle looks like it was plucked straight from a fairy tale.

Built in the mid-1800s by Archduke Ferdinand Maximilian of Austria, the castle was designed as his dream seaside retreat. Inside, you’ll find lavish wood-paneled rooms, velvet-covered walls, and nautical touches that reflect his love for the sea. Most of the interiors are still preserved as they were when he lived here with his wife, Charlotte of Belgium.

The story, however, takes a tragic turn. In 1864, Maximilian sailed to Mexico to become emperor – only to be executed three years later. Charlotte returned to Europe, where she eventually suffered a mental breakdown. Since then, the castle has served as everything from a military base to Allied headquarters before becoming the museum you can visit today.

Even if you skip the interior, the castle grounds are free to explore and absolutely worth the trip. Stroll through lush gardens filled with exotic plants, pause at hidden benches overlooking the sea, and take in one of the most romantic spots in all of Trieste.

2. Step Back in Time at the Roman Theatre of Trieste

• Hours: 24/7
• Cost: Free

Right in the middle of modern-day Trieste, between busy streets and apartment buildings, you’ll stumble upon an ancient surprise, the Roman Theatre of Trieste. Dating back to the 1st century AD, when the city was known as Tergeste, this amphitheater once hosted around 3,500 spectators. It was cleverly built into the slope of San Giusto Hill, making the most of the natural terrain.

Here’s the wild part: for centuries, most of it was buried and forgotten. It wasn’t until the 1930s, during Mussolini’s campaign to unearth Italy’s Roman heritage, that the theatre was fully uncovered.

Today, it’s completely open to the public. No ticket booths, no gates – just this remarkably preserved piece of Roman history casually hanging out between cafés and apartment blocks. It’s not Rome’s Colosseum, and that’s exactly the charm. It’s quiet, often overlooked, but still part of Trieste’s everyday life.

If you’re a history lover (or just enjoy stumbling across ancient ruins during your espresso run), this is one of the most unique things to do in Trieste.

3. Stroll Through Piazza Unità d’Italia

• Hours: 24/7
• Cost: Free

If there’s one place that captures the spirit of Trieste, it’s the Piazza Unità d’Italia, the largest sea-facing square in Europe. Standing here, you might feel like you’ve been dropped into Vienna or Budapest, and you’re not wrong. The grand Austro-Hungarian architecture wraps around the square, telling stories of a time when Trieste was the empire’s prized port.

The square’s name, which means “Square of Italian Unity,” came after Trieste officially joined Italy in 1918, a nod to its complex past and shifting borders. Around the piazza, you’ll find:

• The Town Hall with its elegant clock tower.
  
• The Lloyd Triestino building, once the headquarters of one of the world’s most powerful shipping companies.
  
• The Grand Hotel Duchi d’Aosta, where emperors, poets, and political leaders have stayed.

You don’t need a guided tour here, just grab a gelato or a spritz, find a seat, soak in the Adriatic breeze, and just…exist. At sunset, the square glows gold, and it’s easily one of the most romantic and simple things to do, because sometimes the best things to do in Trieste are the quiet, unforgettable ones.

4. Wander Along the Canal Grande di Trieste

• Hours: 24/7
• Cost: Free

Venice might have its canals, but Trieste has its own charming waterway, the Canal Grande di Trieste. Built in the 1700s, it was designed so ships could sail right into the heart of the city, allowing merchants to unload goods directly in front of their shops.

These days, the canal is more about leisure than trade. Boats bob gently in the water, cafés spill onto the promenade, and locals stroll past as if they own the place (and honestly, some probably do). This is the perfect spot to slow your pace, sip a coffee, or enjoy a spritz before diving back into sightseeing.

Don’t miss the statue of James Joyce on the bridge, a tribute to the Irish writer who lived here for over a decade. He reportedly wasn’t a fan of the weather, but he loved the wine and the people… which feels pretty relatable.

For a relaxed break in your one-day itinerary, the Canal Grande is an easy and scenic stop and a photogenic highlight among the best things to do in Trieste.

5. The Giant Staircase of Trieste

• Hours: 24/7
• Cost: Free

One of Trieste’s most dramatic city features isn’t a castle or café – it’s the Giant Staircase. Built in 1906, this sweeping stone staircase connects the lower city with Piazza Unità d’Italia, giving you a mix of exercise and epic views.

Designed during the Austro-Hungarian era, the staircase was meant to impress and it still does. Curving terraces, ornate stonework, and grand steps make it feel like a royal entrance rather than a public thoroughfare. As you climb, take your time to pause on the terraces, catch your breath, and admire the city rooftops and Adriatic glimpses below.

It’s not just about the view, the staircase itself is a slice of Trieste’s history, showing off the city’s Austro-Hungarian flair and the pride locals have in their architecture. Whether you’re using it as a shortcut or just taking a leisurely stroll, the Giant Staircase is a must-see spot for any one day in Trieste itinerary.

6. Take in seaviews from the Castello di San Giusto

• Hours: Every day 9 AM – 7 PM (summer hours)
• Cost: Castle is €7 for adults
  • Grounds are free to explore

Perched on the hill that shares its name, Castello di San Giusto has been keeping watch over Trieste for centuries. Built by the Habsburgs in the 15th century, this fortress was meant to defend against the Venetians, who were always eyeing this prime stretch of coastline.

The castle’s architecture is a patchwork of styles, a little Romanesque here, some Venetian touches there, thanks to centuries of additions and repairs. Inside, you’ll find defensive walls you can walk along, cannons on display, and jaw-dropping views over the Adriatic and the city’s rooftops.

Beneath the castle, you’ll uncover even more history: the Cathedral of San Giusto and Roman ruins, because in Trieste, history comes in layers.

Whether you tour the inside or simply wander the grounds, this is one of the best vantage points in the city. Time your visit for sunset, and you’ll see why it’s one of the most memorable things to do in Trieste – especially if you bring along a drink to toast the view.

7. Coffee Culture and Historic Cafés

If you think coffee is just a drink, think again. In Trieste, it’s basically a way of life. Back in the 1700s, Trieste was declared a free port under the Austro-Hungarian Empire, making it the main entry point for coffee beans into Central Europe. By the 1800s, it was a hub for roasting, trading, and shipping beans all over the continent.

Fast forward to today, and Trieste is still brewing up a caffeine legacy. This is the birthplace of Illy, one of Italy’s most iconic coffee brands. They’ve been roasting here since the 1930s and even helped develop early espresso machines that shaped how the world drinks coffee.

But what really sets Trieste apart is its local coffee language. A “nero” gets you a straight espresso, a “capo in B” is a macchiato served in a glass. And just like the rest of Italy, if you’re ordering a latte, you better specify or else you’ll get a glass of plain milk.

For the full experience, head to Caffè San Marco, a historic literary café serving thinkers and artists since 1914. Chandeliers, wood paneling, and the quiet clink of espresso cups make it easy to lose track of time. Sip a capo in B, do some people-watching, and soak up the vibes of James Joyce’s old stomping grounds – definitely one of the most cultural things to do in Trieste.

8. A Drink with a View

Trieste knows how to pair cocktails with a view. Near the marina, Pier The Roof puts you right over the water for a front-row seat to the Gulf of Trieste. For something a little higher up (and fancier), 7th Rooftop on top of the Hotello offers panoramic views across the city – though it was closed during our visit, it’s worth checking for your trip.

If history is more your thing, Bar Bastione at San Giusto Castle combines golden-hour views, castle walls, and rooftop vibes for an unforgettable evening. Whether sipping a spritz or just soaking in the sunset, enjoying a drink with a view is an easy way to tick off one of the most scenic things to do in Trieste.

9. Dinner & Sunset Spots

After a full day exploring Trieste’s castles, canals, and cafés, it’s time to wind down with dinner and drinks. Trieste’s coastal location makes seafood a must – think fresh fish, fried sardines, and local specialties that highlight the Adriatic flavors.

We made reservations at Trattoria Nerodiseppia and we started with Sardines in Savour, a local dish served deep-fried and marinated with onions and parsley. It’s intimidating at first – yes, there are bones, but once you get the technique down, it’s delicious. For mains, we ordered the sea bass carpaccio and bigoli pasta with sea bream for something light and flavorful. 

Pair your meal with a crisp Vitoska white wine or a bold Terrano red, and you’re in for a true taste of the region.

What to Eat & Drink in Trieste

Trieste sits at a crossroads of cultures, and its food is proof. Sure, you’ll find pasta and pizza, but the city’s culinary identity is a flavorful mix of Italian, Austrian, and Slavic influences.

Local Dishes to Try

• Jota – A hearty stew of sauerkraut, beans, potatoes, and pork. Comfort food with a touch of Austrian and Slovenian flair.
  
• Cevapcici – Grilled Balkan-style sausage links, usually served with onions and ajvar. Simple, savory, and everywhere in Trieste thanks to Yugoslav roots.
  
• Gnocchi di susine – Plum-stuffed potato dumplings rolled in buttery breadcrumbs and sugar. Dessert disguised as a main dish, and completely worth it.
  
• San Daniele Prosciutto – Think Parma ham’s delicate cousin, often paired with local cheese and bread for a perfect antipasto.
  

Cocktails Unique to Trieste

Trieste has its own twist on spritz culture. Try a Spritz Bianco – white wine with seltzer, no orange liqueur – crisp, simple, and perfect on a hot day. 

Another local favorite is the Pelinkovac spritz, a bitter Balkan herbal liqueur served with soda and a slice of orange. 

For late-night explorers, try a caffè corretto alla Triestina – espresso “corrected” with grappa or cognac. Not quite a cocktail, but a survival strategy after a long day of sightseeing.

Wines of the Region

Right next to the Carso (Karst) wine region, Trieste offers bottles you won’t forget:

• Vitoska – A crisp, dry white with mineral-forward notes, perfect with seafood.
• Terrano – A bold red, slightly sour, almost purple in color, perfect with grilled meats or cured meats.

Both wines are often part of the orange wine trend, natural, skin-contact wines with cloudy amber hues. Keep an eye out for them; they’re some of the best local sips in Trieste.

Where to Stay in Trieste

Whether you’re wandering Roman ruins, climbing castle walls, sipping coffee where Joyce once wrote, or watching the sunset over the Adriatic, Trieste isn’t just a stop on the map; it’s a city that invites you to slow down, explore, and savor every moment. One day is barely enough, but it’s more than enough to fall in love with this unique city – cheers to making the most of your 24 hours in this Adriatic gem!
