Take your time wandering through the Castello district, where you’ll pass through towering old gates and walk past palaces that have stood for centuries.

Cagliari is a place where history and modern life flow together effortlessly. Whether you’re into culture, crave beach days, or love discovering new flavors, this city has something for you. In this blog, we’ll guide you through Cagliari’s top sights— from must-see highlights to hidden gems that make this city truly unforgettable.
What is Cagliari Known for?
At first glance, Cagliari feels like a lively Mediterranean port city, buzzing with energy. Its sun-drenched squares, colorful markets, and café-lined promenades all hint at a place full of life. But beneath the surface lies a story that stretches back thousands of years. From Phoenician merchants and Roman emperors to Pisan nobles and Spanish rulers, each era has left its footprint on the city. Cagliari is a place where history, coastline, and culinary traditions come together in a way that feels both timeless and distinctly Sardinian.
One of the city’s most unforgettable areas is the Castello district, perched high above the rest of Cagliari. Here, you can lose yourself in winding alleys where the past seems to linger in every stone. The centuries-old city walls, massive gates, and stately palaces tell the story of a city long shaped by conflict, resilience, and pride. From the Bastione di Saint Remy, one of the city’s most iconic landmarks, the view over the rooftops and the harbor is breathtaking. For us, this beautiful bastion was—quite literally—the highlight of our visit.
Cagliari’s identity is also deeply tied to the sea. Poetto Beach, the city’s beloved eight-kilometer shoreline, is where locals come to swim, take a stroll, or enjoy an aperitivo with their toes in the sand. Just beyond the beach lies Molentargius Park, a peaceful nature reserve where flocks of pink flamingos glide through the shallow waters of the lagoons. Further along the coast, the dramatic Sella del Diavolo rock formation offers a short but stunning hike with sweeping views over the city and the Gulf of Cagliari.
You might be surprised to learn that Cagliari is also a popular port of call for cruise ships. It’s a good idea to check the cruise schedule if you plan to explore the historic center. We quickly discovered how busy the old town can get when a large ship is docked in the harbor.
And of course, no visit to Cagliari is complete without diving into its food scene. The Mercato di San Benedetto is a feast for the senses, with stalls overflowing with fresh fish, handmade cheeses, and aromatic herbs. Across the city, restaurants serve Sardinian specialties like fregola with seafood, salted bottarga, and delicate culurgiones. In the Marina and Stampace neighborhoods, welcoming wine bars invite you to try local pours such as crisp Vermentino and full-bodied Cannonau.
Things to Do in Cagliari
#1 The Castello District
Castello is the beating heart of Cagliari. Perched high above the rest of the city, this medieval district is a labyrinth of narrow alleyways, vibrant facades, and timeworn squares. Once home to the nobility and military elite, it still carries the grandeur of a bygone era, with stately palaces and fortified walls standing proudly above the surrounding neighborhoods.
Some of Cagliari’s most iconic sights are found here, including the Cathedral of Santa Maria, the Royal Palace, and the towering defenses of Torre di San Pancrazio and Torre dell’Elefante. You’ll also find the city’s Archaeological Museum in Castello, where ancient treasures and historical finds shed light on Sardinia’s deep and fascinating past.
During the day, Castello exudes a peaceful, almost suspended-in-time atmosphere, as visitors meander through its quiet streets and hidden corners. But as evening descends, the mood shifts. The narrow lanes come to life with the hum of music, clinking glasses, and friendly voices, while the scent of freshly made pasta fills the air—offering a warm invitation to linger a little longer and soak in the magic of this hilltop gem.
#2 The Santa Maria Cathedral
The Cathedral of Santa Maria stands as the undeniable heart of the Castello district. Built in the 13th century by the Pisans and later expanded by the Spanish, this stunning structure is a harmonious blend of Romanesque and Baroque styles. Though its grand façade gives the impression of an ancient masterpiece, it is, in fact, a 20th-century reconstruction.
Step inside, and you’ll be transported into a world where art and history seamlessly come together. The marble altars, vibrant frescoes, and intricate sculptures immediately captivate the senses. One particularly fascinating feature is the pulpit, originally crafted for the Cathedral of Pisa, now proudly placed here, adding to the cathedral’s magnificent presence.
The crypt below holds the remains of Christian martyrs, and within the Royal Chapel, members of the House of Savoy are laid to rest. Yet, it is the architecture in the crypt that is especially breathtaking. The walls, adorned with detailed depictions of saints, and the ceilings, featuring intricate patterns and motifs, leave a lasting impression. For those seeking a view that truly captures the beauty of the city, climbing the bell tower is an absolute must.
#3 Bastion of Saint Remy
The Bastione di Saint Remy stands as one of Cagliari’s most iconic landmarks. Built between 1896 and 1902, this impressive structure connects the historic Castello district with the lower parts of the city. While it was originally part of the medieval city walls, it was transformed in the 19th century into a spacious terrace, complete with a grand triumphal arch.
A wide marble staircase (which turned out to be a bit tricky with a stroller) leads up to the Terrazza Umberto I, a panoramic viewing platform offering breathtaking views of the city and the sea. This is the ideal spot to watch the sunset as the sky gradually shifts to hues of orange, and the city is bathed in a warm, golden light.
The bastion was heavily damaged during World War II by bombings, but thankfully, it has been carefully restored and stands proudly today, a symbol of resilience and beauty.
#4 Tower of the Elephant
At the heart of the Castello district, the Torre dell’Elefante towers over the city, standing as a testament to Cagliari’s rich history. This imposing 30-meter structure was built in 1307 by the Pisans to defend the city from Aragonese invasions, and it certainly earned its place in the city’s defenses. With its thick limestone walls and commanding position, the tower was an essential fortress, offering a stronghold against would-be attackers.
The tower’s curious name comes from a small marble elephant that adorns its façade. The reason behind this choice is a mystery—no one really knows why an elephant—but it certainly gives the tower an endearing and distinctive touch. During the Spanish rule, the tower’s role became darker. It was repurposed as a prison and even an execution site. Decapitated heads of criminals were once displayed on the tower’s walls, serving as a gruesome warning to those who dared to defy the law.
#5 Poetto Beach & Molentargius Park
Looking for a day of sun and sand? Poetto Beach is the perfect destination, where both locals and visitors dive into the sparkling Mediterranean waters. Spanning eight kilometers from Cagliari to Quartu Sant’Elena, this idyllic stretch of coastline is an ideal spot for soaking up the sun, enjoying the sea, and unwinding. During the day, it’s a vibrant hub for sunbathers and watersport enthusiasts, while come evening, the beach transforms into a lively scene with beach bars and seaside restaurants offering delicious food and drinks.
Just behind the beach, you’ll find Molentargius Park, a remarkable nature reserve home to salt pans and serene lagoons. Here, you can witness the graceful flamingos, their vibrant pink feathers standing out against the brilliant blue waters. The park is steeped in history, with salt production dating back to Roman times.
For a truly peaceful experience, take a stroll or bike ride through the park’s quiet pathways. Along the way, you’ll spot not only flamingos but also herons and other waterfowl, creating a truly serene atmosphere. A day spent at the beach, followed by a visit to this extraordinary park, offers the perfect blend of relaxation and nature right on Cagliari’s stunning coastline.
#6 Palazzo Civico
The Palazzo Civico, Cagliari’s town hall, is one of the city’s most impressive landmarks. This grand white palace on Via Roma was built in the early 20th century after the old town hall in the Castello district became too small for the city’s expanding needs. Designed to make a statement, the new building truly embodies the grandeur it was meant to convey.
The architecture is a stunning blend of Neo-Gothic and Art Nouveau styles, with elegant arches, intricately carved columns, and towering spires that catch the eye from every angle. Inside, it’s said that visitors can admire beautiful frescoes and artworks showcasing Sardinia’s rich history, though we didn’t personally check if these are open to the public.
Today, the Palazzo Civico is an administrative building and a symbol of Cagliari’s identity. During World War II, the building suffered heavy damage from bombings, but it was carefully restored, preserving its historical and architectural legacy for future generations to appreciate.
#7 Mercato di San Benedetto (San Benedetto Market)
For anyone eager to explore the true flavors of Sardinia, a visit to the Mercato di San Benedetto is a must. As the largest covered market in Cagliari—and one of the biggest in all of Italy—this vibrant marketplace is a feast for the senses. Spread over two levels, it offers an incredible variety of local products, from fresh fish and seafood to regional meats, cheeses, vegetables, and aromatic herbs.
The fish section is especially remarkable. Every morning, Sardinian fishermen deliver their fresh catch, including swordfish, lobsters, sea urchins, and tuna, all available for purchase right there on the spot. The air is infused with the inviting scents of fresh herbs and just-baked bread, while the stalls overflow with quintessential Sardinian treats like bottarga (dried fish roe) and the island’s famous pecorino cheese. Whether you’re a passionate foodie or simply looking to immerse yourself in the island’s culture, this market is an absolute gem you won’t want to miss.
#8 Via Stretta
Via Stretta may very well be the narrowest and most enchanting street in all of Cagliari. Nestled in the heart of the Castello district, this little alley is so narrow that only two people can pass side by side. The buildings along the street are a riot of color, their facades draped with flower-filled pots, tiny balconies, and clotheslines that stretch from one window to the next. In this peaceful corner of the city, you’ll find a cozy, intimate atmosphere—almost as though you’ve uncovered a secret part of Cagliari where time has simply paused.
Although this hidden gem doesn’t appear on many maps, it was highly recommended to us as the perfect spot to soak in the authentic spirit of the city. And it certainly lived up to the hype. Via Stretta feels like something straight out of an old Italian film, exuding a timeless charm that makes it a truly special place to visit.
#9 Chiesa di San Michele
Nestled in the heart of the Stampace district, amidst lively streets and historic buildings, is a hidden baroque treasure: the Chiesa di San Michele. Built in the seventeenth century, this church stands as one of the most remarkable examples of baroque architecture in Cagliari. From the outside, the building may appear understated, but once you step inside, you’re welcomed by an awe-inspiring display of beauty and splendor.
The grand dome, with its striking octagonal base, creates an overwhelming sense of space and light, elevating the entire atmosphere. Inside, the church is a feast for the eyes, with delicate stucco work, gilded accents, and frescoes that bring biblical stories to life. One of the most unforgettable moments for us was visiting the sacristy, considered a masterpiece of Rococo design. This elegant space is open to visitors, and we were fortunate enough to access it through two doors on either side of the main altar, allowing us to fully immerse ourselves in its stunning craftsmanship.
#10 Orto Botanico
Tucked away in the heart of the city, the Orto Botanico offers a lush, green retreat from the lively streets of Cagliari. Founded in 1858, this botanical garden spans five hectares and showcases over two thousand plant species from all corners of the globe.
As you wander through its peaceful pathways, you’ll be greeted by towering palm trees, unique cacti, and the fresh scent of Mediterranean herbs. Winding trails guide you past serene ponds and delightful fountains, creating a sense of tranquility at every turn. But the Orto Botanico isn’t just about the plants—it’s also home to fascinating archaeological gems. Among the foliage, you’ll find remnants of ancient Roman water basins and a mysterious grotto, adding layers of history to this natural haven. It’s a place where the beauty of nature and the whispers of the past come together in perfect harmony.
#11 The Other Districts of Cagliari: Villanova, Marina and Stampace
Cagliari is a city with much more to offer than just the historic Castello district. Villanova, Marina, and Stampace each have their own distinct character, giving you a chance to explore different sides of the city.
Villanova, tucked at the foot of Castello, feels almost like a small village within the city. Its narrow streets are lined with quaint, low-rise houses adorned with pastel-colored facades and vibrant blooming balconies. As you wander through this peaceful neighborhood, you’ll discover cozy cafés, unique craft shops, and charming squares where locals gather to chat and relax. Villanova is one of Cagliari’s quietest districts, making it an ideal place for a leisurely stroll.
Marina, situated right by the bustling harbor, was once home to fishermen and traders, and today it remains a lively district full of energy. With its restaurants, wine bars, and boutique shops, it’s the perfect place to enjoy some of the freshest seafood in Cagliari, or sip an aperitivo while taking in the harbor views. The winding streets and historic buildings give Marina an authentic Mediterranean charm that’s hard to resist.
Stampace is one of the oldest and most traditional neighborhoods in Cagliari. Here, you’ll find ancient churches, hidden courtyards, and a sense of history that fills the air. The neighborhood is still home to old festivals and processions, such as the famous Sant’Efisio celebration held every May. During the day, Stampace has a calm, almost serene atmosphere, but come evening, the trattorias and bars come to life, offering a taste of the city’s local culture and nightlife.
#12 Cagliari’s piazzas
Cagliari is teeming with lively squares where the city’s energy truly comes to life. Whether you’re enjoying a cappuccino in the morning sun, watching the world go by from a café terrace, or soaking in the evening vibe with both locals and visitors, the squares offer the perfect places to slow down and savor the moment.
Piazza Yenne is arguably the most iconic square in Cagliari. During the day, it’s a bustling hub, with shopping streets and cafés drawing crowds, while at night, it transforms into a vibrant social spot, filled with bars and restaurants. It’s the perfect place to enjoy an aperitivo or indulge in a plate of culurgiones, the Sardinian pasta delicacy.
As you explore deeper into the city, you’ll find Piazza Palazzo, the historic soul of the Castello district. Here, some of the city’s most important landmarks stand tall: the Santa Maria Cathedral, the former Royal Palace, and the Archiepiscopal Palace. Steeped in history, this square exudes an undeniable charm and is one of the most atmospheric spots in the old town.
At the base of the Bastione di Saint Remy is Piazza Costituzione, one of Cagliari’s most elegant squares. With the magnificent stairs and arches of the Bastion framing the view, it’s a favored spot for leisurely strolls and photo ops.
A short stroll further brings you to Piazza Carlo Alberto, a charming square framed by colorful buildings. Unlike the more bustling squares, this one offers a serene escape, making it the perfect spot to relax on a bench and soak in the sights and sounds of the city.
Just beneath the city’s ancient walls lies Piazza Indipendenza, a square rich in history and home to the Torre di San Pancrazio and the Archaeological Museum. This spot serves as the perfect starting point for exploring Cagliari’s fascinating past.
For art and history enthusiasts, Piazza Arsenale is a must-visit. Situated near the Citadel of Museums, it’s home to the Archaeological Museum and the Pinacoteca Nazionale, both brimming with impressive collections that tell the story of the city’s cultural heritage.
Cagliari’s smaller squares each hold their own unique appeal. Piazza Lamarmora in Castello feels intimate and full of character, while Piazza San Domenico in Villanova is a peaceful green retreat, crowned by a beautiful church. Piazza San Giacomo, with its pastel-hued buildings, radiates a classic Mediterranean charm. Piazza San Sepolcro, tucked away in the heart of the old town, is a hidden treasure, lined with centuries-old structures. And for those seeking a quiet respite from the crowds, Piazza San Cosimo offers a tranquil corner of the city, perfect for slowing down and unwinding.
#13 Sella del Diavolo
The Sella del Diavolo, or “Devil’s Saddle,” stands as one of the most captivating natural landmarks in Cagliari. This striking promontory, nestled between Poetto Beach and the Calamosca district, owes its intriguing name to an age-old legend. According to the tale, the devil tried to seize control of the breathtaking Gulf of Cagliari, only to be chased away by angels. As he tumbled, he lost his saddle, which now juts out dramatically as a rock formation overlooking the sea.
For those who enjoy an active adventure, a hike to the top is an absolute must. The trail begins at Calamosca and meanders through lush Mediterranean vegetation, taking you past ancient viewpoints and remnants of the area’s rich history. Once you reach the summit, you’ll be rewarded with panoramic views of the city, the sparkling sea, and the Molentargius salt pans, where flamingos often roam.
The path is manageable for anyone in good physical shape, but during the warmer months, it’s advisable to start early in the morning or around sunset. Not only will you avoid the heat, but you’ll also be treated to the most stunning light, perfect for photography or simply soaking in the view.
#14 National Archaeological Museum
To truly grasp the essence of Cagliari, a visit to the Museo Archeologico Nazionale is essential. Nestled within the Citadel of Museums, this treasure trove invites you to explore thousands of years of Sardinian history. From the mysterious Nuragic civilization to Roman and Phoenician relics, it offers an immersive experience into the island’s rich cultural heritage and how it has been shaped across the ages.
Among the museum’s most striking exhibits are the bronze figurines of Nuragic warriors, over three thousand years old. These intricate sculptures highlight the unique artistry and skill of ancient Sardinian societies. You’ll also encounter beautiful Phoenician jewelry, delicate Roman glassware, and ancient inscriptions that provide fascinating insights into the island’s past.
The museum is thoughtfully organized, making it easy to explore, with informative displays available in both English and Italian. A visit here is the perfect way to enrich your understanding of everything you’ll see throughout Cagliari and the wider Sardinia—from the remnants of the Punic necropolis to the scattered Roman ruins throughout the city. It’s an ideal stop for those seeking more than just sun and sea, offering a deeper connection to the island’s vibrant history.
#15 Tuvixeddu Necropolis
Just a short distance from Cagliari’s city center, perched on a hill, lies one of the city’s most captivating archaeological treasures: the Tuvixeddu Necropolis. This ancient Phoenician-Punic burial site is the largest of its kind in the Mediterranean and dates back to the 6th century BC.
Hundreds of tombs are carved into the limestone cliffs, with some featuring staircases leading down to deep, solemn burial chambers. Many of those laid to rest here were accompanied by valuable grave goods, such as intricate jewelry, ancient amphorae, and weapons—offering a glimpse into the wealth and sophistication of the Phoenician and Carthaginian civilizations that once flourished in this area.
Though parts of the necropolis have been lost to the encroachment of modern development, Tuvixeddu still stands as a fascinating place to explore. Meandering pathways guide you through the ancient graves, while informative signs shed light on the burial customs and rituals practiced thousands of years ago. Set within a park, the necropolis offers the perfect blend of history and nature, allowing you to enjoy both a stroll and a deep dive into the past. The striking contrast between the timeless tombs and the modern city surrounding them makes Tuvixeddu a truly unique and thought-provoking sight in Cagliari.
