The Cagliari Walking Tour Stop by Stop, from Marina to Castello

  1. 1

    Via Roma

    Via Roma in Cagliari, stop 1 on the self-guided walking tour

    Start under the arcades. The stretch of Via Roma that faces the port, lined with porticoed palazzi, cafés and shops, is counted among Cagliari's “drawing rooms”, the place where the city comes to stroll and sit. This showpiece runs from the corner of Viale Regina Margherita in the east to Largo Carlo Felice in the west and marks the southern edge of the Marina quarter. Beyond it the street carries on west into Stampace, past Piazza Matteotti with the Palazzo Civico and the railway station.

    Look up at the façades as you walk. The palazzata went up between 1893 and 1988, the year the Palazzo del Consiglio regionale was finished, and its eclectic buildings mix classical and Renaissance elements with Liberty decoration. Along one row of arcades you can read almost a century of changing taste.

    None of this existed before the 1880s. The ground was taken up by the walls and bastions of the Marina, pulled down from 1880 for reasons of hygiene and because a royal decree of 31 December 1866 had ended Cagliari's role as a military stronghold. Between the harbour bastions and the houses ran the street's ancestor, Via San Francesco al Molo, named after the church of San Francesco di Paola. Further west it narrowed into Via delle Conce, where hides were tanned, and low houses with cheap trattorie leaned against the walls.

    Via Roma opened on 6 January 1883, and the same demolition gave the city Largo Carlo Felice and Viale Regina Margherita as well. From here the route turns into Stampace: 660 m, about 10 minutes, to a doorway that leads underground.

    Cripta di Santa Restituta

    Cripta di Santa Restituta in Cagliari, stop 2 on the self-guided walking tour

    In the Stampace quarter, beside the church of Santa Restituta and entered from Via Sant'Efisio, you go below street level into a space hollowed out of the rock. It is a modest site rather than a showpiece, and that is its charm: one cave holds the whole sweep from the Punic city to the twentieth century.

    In Punic times this was a quarry, cut for building stone. Later it became a place of worship, and at another stage it served as a store for amphorae. During the Second World War the people of Cagliari sheltered here from air raids, so the same rock that once supplied the city later protected it.

    Go in if you like places where history shows in layers of use rather than in grand architecture. The visit is cheap and short, and it sets the tone for the rest of the walk, which keeps returning to the stone of this hill.

    Back in daylight, the longest leg of the route follows: 890 m, about 15 minutes, to the Roman Amphitheatre.

    Roman Amphitheatre

    Roman Amphitheatre in Cagliari, stop 3 on the self-guided walking tour

    The arena is half cut into the living rock; the rest was built of white limestone. Its south façade has vanished, but it once rose more than 20 metres. Between 8,000 and 10,000 spectators fitted inside, close to a third of the people of Roman Carales. It was built in the first or second century AD, when Sardinia and Corsica had long been a single Roman province.

    Read the seating as a social map. Just above the arena sat the podium, reserved for the city's leading figures. Free citizens took their places by rank in the lower, middle and upper sections of the cavea, while women and slaves were sent to the covered tier at the very top. Below them, animals fought animals, gladiators fought each other and specialist fighters were brought in from outside Sardinia; executions were carried out before a cheering crowd, and plays were staged here too.

    As Christianity spread, gladiator fights fell out of favour until Emperor Valentinian III banned them by law in 438 AD. The empty building became a quarry: Byzantines, Pisans and Aragonese all took its stone for new fortifications. By the nineteenth century it lay completely buried. The city bought the site and handed the excavation to the canon Giovanni Spano, whose team found coins and a mass of thin marble slabs that had once lined the arena. In the early 2000s an iron and wooden structure was laid over it for summer concerts and shows.

    This is the interior to choose if you only pick one on the lower half of the route, and the ticket is cheap. Then walk 600 m, about 9 minutes, to the National Archaeological Museum, where many of the island's finds are kept.

    National Archaeological Museum

    National Archaeological Museum in Cagliari, stop 4 on the self-guided walking tour

    This is the most important archaeological museum in Sardinia. Since 1993 it has occupied part of the Cittadella dei Musei, in spaces designed by the architects Piero Gazzola and Libero Cecchini. Its cases hold many of the island's key finds, mostly from the provinces of Cagliari and Oristano but with precious pieces from the rest of Sardinia too, spanning prehistory to the Byzantine era.

    The collection is older than its building. In 1800 Viceroy Carlo Felice took up a proposal by Cavaliere Lodovico Baylle and set up a Cabinet of Archaeology and Natural History in a room of the viceregal palace, entrusted to Cavaliere De Prunner. It was a cabinet of curiosities in the spirit of the age, mixing antiquities, minerals and animals without strict scientific order, and in 1802 it opened to the public, a remarkable step for its time.

    In 1805 the viceroy gave the collection to the Royal University of Cagliari, which moved it to Palazzo Belgrano in 1806. The rooms grew in 1857, and in 1858 the minerals were split off to other university sites, leaving the antiquities with spaces of their own.

    Go in if you want to understand what you have seen so far and what lies across the island; allow about an hour and a quarter. From here it is 380 m, about 5 minutes, to the old Jewish quarter, passing the Museum of Anatomical Waxes on the way.

    Jewish Ghetto (Il Ghetto)

    Jewish Ghetto (Il Ghetto) in Cagliari, stop 5 on the self-guided walking tour

    Down from the Cittadella, the route turns into Via Santa Croce and enters the old Jewish quarter. Here the lanes themselves are what you came to see, so walk slowly: the stretch is short and easy to rush.

    The Centro Comunale d'Arte e Cultura Il Ghetto, the space that normally explains the quarter, is currently closed for building works, so this stop is one to take in from outside. The quarter's lanes remain open to walk, and the walls of Castello rise just above them.

    From here it is only 230 m, about 3 minutes, into the Castello District.

    Castello District

    Castello District in Cagliari, stop 6 on the self-guided walking tour

    Castello is the chief of Cagliari's four historic quarters, set on a limestone hill about a hundred metres above the sea. Locals call it simply Castello, without the article, and in Sardinian it is Castéddu 'e Súsu, the upper castle. You still enter through medieval gates in the walls that ring most of the quarter and set it apart from the rest of the city.

    The Pisans founded it in the thirteenth century and fortified it with walls, towers and bastions. They moved the seats of civil, military and religious power here from Santa Igia, the capital of the Giudicato of Càlari, which they had destroyed, and with it ended the giudicato itself.

    After that every ruler governed from this hill: the Pisans from 1215, the Aragonese and Spanish from 1326, the Austrians from 1708, the Spanish once more from 1717 and the House of Savoy from 1720 until 1861. Until after the Second World War Castello held the palaces of power and the homes of the nobility, so closely tied to the city that Cagliari's Sardinian name is simply Casteddu.

    Much of that role continues. The Palazzo Reale on Piazza Palazzo houses the Prefecture and the council chamber of the Metropolitan City of Cagliari, and the University of Cagliari runs its rectorate from an eighteenth-century palace in the quarter. The cathedral stands on the same square, just 150 m away, about 3 minutes on foot.

    Cagliari Cathedral

    Cagliari Cathedral, stop 7 on the self-guided walking tour

    The Cathedral of Santa Maria and Santa Cecilia is the seat of the Archbishop of Cagliari. The Pisans built it in the thirteenth century in Pisan Romanesque style inside their stronghold, Castel di Castro, and it became the cathedral in 1258, after they had destroyed Santa Igia and its cathedral. The façade you see is younger than it looks: the old one was pulled down in the early twentieth century and replaced in the 1930s by a Neo-Romanesque front inspired by Pisa Cathedral.

    The building kept changing. In the fourteenth century a transept turned it into a Latin cross with two side entrances, and the first chapel, in Italian Gothic, went into the left arm. The right arm was finished after the Aragonese conquest, with two more chapels. In 1618 the presbytery was raised to make a sanctuary for martyrs' relics, and between 1669 and 1704 the church was remodelled in Baroque style, with a dome over the crossing and the Gothic chapels removed.

    Go inside: entry is free, and the main treasure deserves the detour. The pulpit of Master Guglielmo was carved in the twelfth century for Pisa Cathedral and brought to Cagliari in 1312, where it stood by the third column of the nave. In 1669 it was split into two pulpits. Look for the four marble lions that once carried it, now at the foot of the presbytery balustrade.

    The last leg is 420 m, about 6 minutes, to the Bastione di Saint Remy.

    Bastione di Saint Remy

    Bastione di Saint Remy in Cagliari, stop 8 on the self-guided walking tour

    The walk ends on the monumental bastion that is counted among the symbols of Cagliari. It is part of the fortifications that protected Castello and stands between Via Mario De Candia and Piazza Costituzione, on the edge of the Villanova quarter. Its name honours Filippo Guglielmo Pallavicino delle Frabose, baron of Saint-Rhémy-en-Bosses and the first Savoyard viceroy of the Kingdom of Sardinia.

    It sits on sixteenth-century Spanish defences guarding the south side of the walled city: the bastions of Santa Caterina, dello Sperone and della Zecca, which belonged to the crown until fortified towns were abolished in 1866. The earth bank at their foot was known in Sardinian as muntonàrgiu, the rubbish heap, because the city used it as a dump.

    Each bastion has its own story. The one once called the baluarte del Trabuc or the terraple de la Fontana bona was built between 1530 and 1532 under Aragonese rule, facing today's Piazza Costituzione, and it has suffered subsidence over the centuries because of the spring that gave it its name. From the Terrazza Umberto I you reach the Santa Caterina bastion, named after a seventeenth-century convent that no longer exists, where Roman and medieval remains of shrines, graves and defences lie in the ground.

    The bastion once known as the Leona was begun early in the sixteenth century on the orders of Viceroy Juan Dusay. It was criticised for protecting the city poorly, and in 1549 it finally received a parapet and cannon.

Shorter Ways to Walk Cagliari

The full route links two quite different halves: Roman and underground Cagliari below, the walled Castello on its hill above. If time or budget is tight, pick one half or walk everything without going inside.

Castello and the ramparts

Stops: 5, 6, 7, 8

For anyone with an hour or a free afternoon. Start at the Jewish Ghetto lanes and walk through Castello to the cathedral and the Bastione di Saint Remy: 12 minutes of walking in total, and nothing here needs a ticket. Go inside the cathedral; it is free.

Roman and underground Cagliari

Stops: 1, 2, 3, 4

For history lovers who care more about Punic quarries and gladiators than about palaces. From Via Roma to the museum is 34 minutes on foot. The crypt, the amphitheatre and the museum each charge admission.

The whole route from outside

Stops: 1, 2, 3, 4, 5, 6, 7, 8

For a first look at the city on a small budget. Walk all eight stops in 51 minutes, view the crypt, the amphitheatre and the museum from outside and only step into the free cathedral; with short pauses you finish in under two hours.

How Long Does This Cagliari Tour Take with the Interiors?

The pure walking time is 51 minutes, and most of it falls in the first half: the two longest legs lead from Via Roma to the crypt and on to the amphitheatre. Once you reach the museum, the stops in Castello sit only a few minutes apart.

With time inside the crypt (about 20 minutes), the amphitheatre (about 35), the museum (about an hour and a quarter) and the cathedral (about 20), plus short pauses on the streets and the bastion, the full walk takes about four hours. Leave Via Roma at 10:00 and you stand on the Bastione di Saint Remy at around 14:15.

The Castello half on its own takes about an hour, the Roman half about two and a half hours with all three tickets, and the whole route seen from outside fits into less than two hours.

Before You Set Off in Cagliari

  • Start and finish: Begin on Via Roma and end on the Bastione di Saint Remy. You can join at any stop, but this order takes you from the harbour up into Castello. When you are done, the GPS navigation in your browser leads you back to the start if you like.
  • Best day and time: Start in the morning, once the crypt and the amphitheatre have opened, so you can see both before lunch and still have time for the museum and Castello.
  • Tickets: Three interiors charge admission: the crypt, the amphitheatre and the museum. Everything else on the route is free.
