An urban island on a hill with medieval Pisan towers, Spanish ramparts, and the Giants of Mont'e Prama, the oldest statues in the Mediterranean. Cagliari is much more than an airport.
Plan your trip →Cagliari Castello is one of the most extraordinary historic quarters in the Mediterranean, and almost no foreign tourist knows it before arriving. Perched on the hill that dominates the city of Cagliari and its gulf, the Castello quarter has kept its medieval urban structure intact: Pisan towers, 16th-17th-century Spanish ramparts, the Viceroy's palace, the cathedral, two excellent museums, and a panoramic view over the whole island that on clear days reaches the coasts of Corsica. Cagliari is the gateway to Sardinia for anyone arriving by plane or by ferry from the mainland, few stay long enough to understand what's in front of them.

From Piazza dell'Indipendenza, the heart of the quarter, the medieval lanes branch off with the typical Cagliari houses in limestone. The Cathedral of Santa Maria dell'Assunzione has Pisan origins from the 13th century with later Baroque alterations. The Palazzo di Città, the Palazzo Regio, and the Tridentine Seminary complete the architectural picture of the square.
The Bastione Saint Remy, the great belvedere terrace built by the Spanish, offers the most beautiful view of the city: the Gulf of Cagliari, the Santa Gilla lagoon, the salt flats, and in the distance the Sardinian hills. At sunset it's one of the most beautiful spots in Sardinia.
The National Archaeological Museum of Cagliari (MANN) is the most important museum in Sardinia: it holds the most complete collection of Nuragic bronze figurines in the world, the Giants of Mont'e Prama (Nuragic stone statues from the 9th century BC, some of the oldest life-size human statues in the Mediterranean), and Phoenician, Roman, and Punic material of the highest quality.
In Cagliari's Castello quarter you'll see: the medieval Pisan towers (the Torre dell'Elefante, the Torre di San Pancrazio), the Bastione Saint Remy with the view over the gulf, the Cathedral, the National Archaeological Museum with the Nuragic bronze figurines and the Giants of Mont'e Prama, and the National Pinacoteca with medieval and modern Sardinian art.
Settlement on the hill of Cagliari is documented from the 6th century BC, with the Phoenicians and then the Carthaginians using the strategic position to control the gulf. The Roman city (Karalis) developed mainly on the plain below. The medieval Castello took shape in the 13th century when the Pisans, who controlled the city in their struggle with Genoa, built the two defensive towers and the hill's walls. In 1324 the city was conquered by the Crown of Aragon, which made it the capital of the Regnum Sardiniae et Corsicae. The very long Spanish period (1324-1718) left its mark on the ramparts, the noble palaces, and the cathedral. The Bastione Saint Remy was built between 1899 and 1902 to a design by the architect Pietrino Leonardi, reuniting two Spanish ramparts with the great triumphal arch that is its main facade.
Cagliari's Castello quarter is reached on foot from the lower town in 15-20 minutes of climbing, or by the elevator from Via Roma (free). The area is a ZTL, it's practically impossible to reach by car. From Cagliari Elmas airport to the city center: train or CTM bus, about 10 minutes and €1.30. Cagliari's port is a 10-minute walk from the Bastione Saint Remy.
Absolutely yes. Cagliari is a city with an extraordinary medieval quarter, excellent beaches 15 minutes from the center (Poetto, the very long city beach), first-rate museums, and a high-quality local cuisine (bottarga, fresh tuna, fregola with seafood, myrtle liqueur). Giving it at least one night completely changes your perception of what the Sardinian capital is.
How do you buy an Italian SIM as a tourist? Italian SIMs are bought at TIM, Vodafone, or WindTre stores or at tobacconists with an ID document. The tourist plans (10-30 GB for €15-25) work well. European tourists with an EU data plan don't need one. Americans with AT&T or T-Mobile international plans find it more convenient to use roaming than to switch SIMs.
How do regional trains work in Italy? Regional trains (Trenitalia's Regionale and Regionale Veloce) need no seat reservation, you buy the ticket and get on. The ticket must be validated before boarding in the yellow machines at the station. Forgetting to validate can cost a fine of €50+ even if the ticket is paid. Regional trains are cheap (€5-15 for 1-2 hour routes) and cover destinations not reached by high-speed rail.
What does "ZTL" mean in Italy? ZTL (Zona a Traffico Limitato) is an urban area where traffic is restricted to residents and authorized vehicles. Cameras record the plates of vehicles entering and the fines arrive by mail through the rental company weeks after the trip (€80-300 per violation). Before driving into any Italian historic center, check the ZTL routes on Google Maps or on the town's website.
How do you use the museum card in Italian cities? Florence, Rome, Venice, Naples, and Turin have multi-site museum cards that give access to several museums at a reduced price with priority booking. The Firenze Card, the Roma Pass, and the Torino Museum Card are the best value if you plan to visit more than 3-4 paid museums in the same city in 2-3 days.
How does health insurance work in Italy? EU tourists with a European Health Insurance Card (EHIC) have free access to the Italian National Health Service. Non-EU tourists (Americans, British, Australians) must have travel health insurance, in the event of hospitalization without coverage the costs can be very high.
1. The principle of seasonal eating: Italian cooking is radically seasonal, not as a gastronomic choice but as deep tradition. Ordering strawberries in January or porcini mushrooms in March is possible, but those strawberries probably come from Spain and those porcini are frozen. Eating what's in season, artichokes in spring, tomatoes in August, mushrooms in autumn, truffles in winter, guarantees the best quality.
2. The North-South difference in restaurant service: In the North (Milan, Turin, Bologna) restaurant service tends to be faster, more professional and formal, similar to the European standard. In the South (Naples, Palermo, Bari) it's more relaxed, informal, and slow by northern European standards. This isn't inefficiency: it's a different cultural rhythm. Going to a restaurant in the evening in the South means being there 2-3 hours, plan accordingly.
3. The museums closed on Monday: Most Italian state museums are closed on Monday. Plan your itinerary accordingly, Monday is the best day for walks in the historic centers, markets, churches, and outdoor visits.
4. The dress code in churches: Italian churches enforce the dress code (shoulders and knees covered) with growing strictness. In many major churches (St. Peter's, Assisi, Orvieto) there are staff at the entrance who turn away anyone not appropriately dressed. A sarong or a light scarf in your backpack solves every problem in any season.
5. The price of water in restaurants: In Italy water in restaurants is paid for, it isn't free as in many English-speaking countries. A 0.5l bottle costs €1-3 depending on the restaurant. You can ask for tap water (acqua del rubinetto) for free, it's drinkable in almost all of Italy. The public drinking fountains in Italian cities provide free drinking water.
The rule of alternation: Alternate city and country, art and nature, museums and markets. Three days in Florence followed by two days in Chianti then one day in Siena, that's a Tuscan itinerary that works. Three days in Florence, one day in Assisi, two in Rome, one in Naples: that's a time-bank itinerary where every transition costs energy and every place stays superficial.
Book the food experiences like museums: Pasta classes, wine tastings at the cellar, market breakfasts with local producers, these experiences are booked 2-4 weeks ahead in peak seasons. The best Tuscan and Piedmontese wineries have waiting lists. The same rule applies to starred restaurants: Osteria Francescana in Modena or Dal Pescatore in Canneto sull'Oglio are booked months in advance.
Learn the context before you leave: A book, a film, a TV series set in the place you're visiting radically changes the depth of the experience. "Elena Ferrante" for Naples, "Gadda" for Milan, "Sciascia" for Sicily, "Pavese" for Piedmont, Italian literature is a key to understanding a place that no guidebook can replace.
Plan Sundays carefully: Sunday in Italy has a completely different rhythm from the other days, many shops close, traditional restaurants are often full of local families (a good sign), the neighborhood markets close. Sunday morning is perfect for churches (full of worshippers, not just tourists), parks, and long breakfasts. Plan to eat before 12:30 or book ahead, the trattorias fill up fast.
Italy is consistently among the top 5 countries in the world for international arrivals, with about 57-60 million foreign tourists a year. 70% concentrate in 10 main destinations (Rome, Venice, Florence, Milan, Naples, Amalfi, Cinque Terre, Sicily, Sardinia, Lake Como). This means that 30% of Italian territory, including extraordinary medieval villages, little-known UNESCO sites, and excellent regional cuisines, is virtually untouched by mass tourism. Slow travel, off-season and off the main axes, is the frontier of travel in Italy in 2025.

Should I bring euros in cash or are cards enough? Always bring a minimum of cash (€100-200) for markets, tips, local transport, and small businesses. Credit and debit cards are accepted almost everywhere in the main cities. In rural areas, small villages, and traditional markets, cash is still preferred or required. ATMs (bancomat) are found in every town, withdraw in euros directly from the Italian ATM to avoid exchange fees.
Is it better to rent a car in Italy? A car is useful for the interior, the medieval villages, the wine areas, and any destination not reached by train. It's absolutely counterproductive in the big cities (ZTL, parking, traffic). The ideal strategy: train between the big cities, a car rented locally to explore the surrounding countryside.
How much daily budget do you need in Italy? Backpacker budget: €60-80/day (hostel, street food, free museums). Mid-range budget: €120-180/day (3-star hotel, local restaurants, paid museums). Comfort budget: €250-400/day (4-star hotel, quality restaurants, private experiences). The most underestimated cost is transport, fast trains, taxis, and airport transfers add up quickly.
