Cagliari: Sardinia’s Historic Capital

Cagliari, Sardinia’s capital, rises from the Gulf of Angels in layers. Down by the harbour are the arcaded streets of the Marina quarter; above them, on a limestone hill, sits Castello, the walled citadel that Pisan merchants fortified in the thirteenth century and that Aragonese and Savoyard viceroys later ruled from. Within a short walk are a rock-cut Roman amphitheatre, a cathedral holding a twelfth-century pulpit carved for Pisa, and the island’s principal archaeological museum. This guide covers what to see in Cagliari, Sardinia, and what to check before you go. On our Mediterranean Islands of Malta, Sicily, Sardinia & Corsica tour, Cagliari is the group’s base for three nights, from Day 12 to Day 14.

Getting your bearings in Cagliari, Sardinia

Cagliari’s historic centre is made up of four old quarters: Castello on the hilltop, Marina, the old port district, below it, Stampace to the west and Villanova to the east. The city’s role as a port is far older than any of them: Phoenician traders had a settlement here, known later as Karalis, and, probably under Julius Caesar, it became a Roman municipium, its citizens rewarded for backing him in the civil war against Pompey.

The shape of the city you walk through today comes mostly from the Middle Ages. In 1216 or 1217 merchants from Pisa founded a fortified town on the hill, Castel di Castro, and over the following century they ringed it with walls and towers. The Crown of Aragon besieged the city from 1324 and took it in June 1326, making Cagliari the seat of its new Kingdom of Sardinia. Spanish rule lasted almost four centuries. Under the 1718 Treaty of London the island passed to Victor Amadeus II, Duke of Savoy, who took formal possession in 1720; his successors bore the title King of Sardinia until the Kingdom of Italy was proclaimed in 1861. For the long prehistory before all of this, our guide to the Bronze Age Nuragic civilisation of Sardinia is the place to start.

The Castello quarter and its Pisan towers

Castello is still a walled town, and the clearest survivors of its Pisan defences are two towers designed by the Cagliari architect Giovanni Capula. The Torre di San Pancrazio, on the north-eastern side, carries an inscription dating it to 1305. The Torre dell’Elefante, on the south-west, followed in 1307. Both were built of white limestone from the Bonaria hill when Pisa feared a Catalan-Aragonese attack, and both are open on the town side, showing their timber floors. San Pancrazio rises to about 37 metres; the Elephant Tower is around seven metres lower and more finely finished.

The Elephant Tower takes its name from the small carved elephant set on a ledge above its gateway. From the sixteenth century, under Spanish rule, San Pancrazio served as a prison. At the time of writing, Sardinia’s regional heritage site lists only the Elephant Tower as open to climb, and the Ministry of Culture’s page for San Pancrazio describes it as temporarily closed. Both are worth seeing from the street regardless.

Between the towers, Castello is a grid of narrow streets lined with tall, pastel-washed palazzi. At the northern end, the Cittadella dei Musei occupies the site of the Savoyard royal arsenal of 1727.

Bastione di Saint Remy and the views from Castello

The most photographed structure in Cagliari is also one of its youngest. The Bastione di Saint Remy was built between 1896 and 1902 on top of two late-sixteenth-century Spanish bastions, to designs by the municipal engineers Giuseppe Costa and Fulgenzio Setti, developing an idea first proposed by the architect Gaetano Cima. It is named after the Baron of Saint Remy, the first Piedmontese viceroy of the island. A broad double stairway climbs from Piazza Costituzione through a triumphal arch to the Passeggiata Coperta, a covered gallery that served as an infirmary during the Second World War.

Above the gallery, the Terrazza Umberto I looks south and east over the roofs of Villanova and Marina to the harbour, the gulf and, on a clear day, the salt pans beyond. Allied bombing in 1943 badly damaged the stairway and arch, which were rebuilt after the war. The terrace is best in the late afternoon, when the limestone turns gold.

The Cathedral of Santa Maria

Cagliari’s cathedral stands on Piazza Palazzo, in the heart of Castello, beside the former royal palace. The church is documented from 1255 and was enlarged by the Pisans over the following century; their bell tower, parts of the west wall and the portals of the transept still survive. Its marble front looks medieval but is not: a Baroque facade of the early 1700s was taken down in the early twentieth century and replaced in the 1930s with the present neo-Romanesque design, modelled on the cathedrals of Pisa and Lucca.

Inside, the great treasure is the pulpit carved by the sculptor Guglielmo between 1159 and 1162 for the cathedral of Pisa. Pisa gave it to Cagliari in 1312, and in 1669 and 1670 it was divided into two pulpits, which now stand either side of the main door; the four lions that once carried its columns were moved to the steps of the presbytery. Below the altar, the Santuario dei Martiri is a crypt cut into the rock in 1618, divided into three chapels and lined with niches holding the relics of martyrs found in the city’s early Christian cemeteries.

The National Archaeological Museum and the Nuragic bronzes

The Museo Archeologico Nazionale di Cagliari, in the Cittadella dei Musei on Piazza Arsenale, holds more than 4,000 finds spanning almost 7,000 years of Sardinian history, from Neolithic mother-goddess figures to Phoenician and Punic jewellery, Roman sculpture and Byzantine objects. Its most celebrated pieces are the bronzetti, the small bronze figures made by the Nuragic people. They show chieftains in cloaks, archers, warriors with round shields, women at prayer, animals and model boats with animal-head prows, and they are the closest thing to a self-portrait the island’s Bronze Age society left behind.

Among the best known are the eight figures found in 1849 at the foot of Monte Arcosu, near Uta, including the roughly 40-centimetre capo tribù, or tribal chief. The museum also holds the Nora Stone, a Phoenician inscription found at Nora that bears the earliest known form of the island’s name, written SHRDN.

Can you still see the Mont’e Prama giants in Cagliari?

No: the Mont’e Prama statues are no longer in Cagliari. These large stone figures of boxers, archers and warriors, found in 1974 on the Sinis peninsula near Cabras, were long divided between the Cagliari museum and restoration laboratories. In 2026 the whole group was brought together at the Museo Civico Giovanni Marongiu in Cabras, on the west coast, which opened its new display to the public on 5 April 2026, with a larger permanent gallery planned to follow. Seeing them now means a separate journey to Cabras, near Oristano.

Is the Archaeological Museum open every day?

At the time of writing, the National Museums of Cagliari list the archaeological museum as open daily, with the ticket office closing about 45 minutes before the galleries. However, the museum is in the middle of a re-display: its official notice says that the third floor and part of the ground floor cannot currently be visited. Check the museum’s website shortly before your visit to see which rooms are open, and note that groups need to book in advance.

The Roman amphitheatre

On the southern slope of the Buoncammino hill, between Castello and Stampace, lies Cagliari’s Roman amphitheatre. Built between the late first and early second century AD, it was partly carved out of the living rock and partly built in limestone blocks, and it could hold around ten thousand spectators for gladiatorial games, animal fights and executions. Later quarried for stone, it survives mainly as its rock-cut seating, arena and the chambers beneath.

The city approved a restoration programme in late 2024, and access has varied while that work proceeds, so check with the city’s tourism office before planning a visit.

Poetto beach and the Molentargius flamingos

Cagliari is one of the few Mediterranean capitals with a major beach inside the city. The Poetto runs for about eight kilometres of pale sand and shallow water between Cagliari and Quartu Sant’Elena, backed by a modern promenade. At its western end, the limestone headland called the Sella del Diavolo, the Devil’s Saddle, rises above the small harbour of Marina Piccola.

Behind the beach lie the lagoons and salt pans of the Parco Naturale Molentargius-Saline, around 1,600 hectares between Cagliari and Quartu. Salt has been gathered here since Phoenician times, and industrial salt works ran from 1830 until 1985. The wetland was listed under the Ramsar Convention in 1977 and became a regional park in 1999. Its best-known residents are the greater flamingos, which both feed and nest here, alongside slender-billed gulls, black-winged stilts and egrets. Trails are free to walk, and guided visits on foot, by bicycle, by boat along the canals and by electric bus are offered from the park’s education centre.

Is Cagliari’s Castello quarter hard to walk?

Castello is steep, but public lifts take much of the effort out of the climb. The routes up from Viale Regina Elena to the Bastione di Saint Remy and from the Santa Chiara area to Via Cammino Nuovo both have lifts, though individual lifts are taken out of service from time to time. Once on top, the streets are fairly level but paved in stone, so shoes with a good grip are worth wearing, and the stairway of the Bastione di Saint Remy is long.

How many days do you need in Cagliari?

Two full days is a comfortable minimum for the city itself: one for Castello, the cathedral and the museum, and another for the amphitheatre, the lower quarters, the Poetto and Molentargius. A third day allows an excursion to Nora, the Phoenician and Roman town on a headland near Pula, about a half-hour drive south-west, whose theatre, baths and mosaic floors make it one of the island’s most rewarding archaeological sites.

Cagliari on Days 12 to 14 of the tour

Day 12 is a travel day. There are currently no direct flights between Sicily and Sardinia, so the group flies to Cagliari by way of Rome or Milan, is met on arrival and transferred to the hotel, where dinner is included. Day 13 begins with a guided tour of Cagliari’s main sights, including the National Archaeological Museum, followed by a group lunch at a local restaurant and free time to explore the city on your own; the rest of the day is at leisure, which leaves room for the Bastione di Saint Remy at sunset or a walk on the Poetto. On Day 14 the group visits Nora, then follows the scenic coastal road to Capo Spartivento before returning to Cagliari for a free evening. A local guide works alongside the Odyssey Program Leader, and the tour is rated Level 3, Moderate to Challenging, with up to six hours of activity a day over varied terrain.

From Cagliari the route turns inland to the UNESCO-listed nuraghe of Su Nuraxi at Barumini and on to Fonni. Our day-by-day Sardinia itinerary from Cagliari to Alghero sets out how the island stages fit together, and our guide to things to do in Sardinia beyond the beach looks more closely at Nora and Barumini.

Cagliari rewards the traveller who arrives curious about how islands are governed from the sea: Phoenician, Roman, Pisan, Aragonese and Savoyard rulers all held this harbour, and each left its mark on the hill above it.
