Cagliari — capital and principal port of Sardinia, Italy

Cagliari is Sardinia’s largest city and regional capital, known for its historic hilltop quarter, important port and airport, Mediterranean climate, university and coastal attractions.

Cagliari is the principal city and administrative capital of the island region of Sardinia in Italy. Its name in the Sardinian language is Casteddu, literally “castle,” a reference to the fortified old town that crowns the city. Cagliari functions as a cultural, academic and economic hub for the island: it hosts the historical University of Cagliari (founded in the early 17th century) and serves as the seat of the Roman Catholic archdiocese of Sardinia, a bishopric with origins in late antiquity. The city also has an important maritime role, with one of the main ports in the western Mediterranean and an international airport at Elmas (Cagliari Elmas).

Geography and climate

Cagliari lies on the southern coast of the island within the Italian region of Sardinia and the country of Italy. Its municipal area covers about 85.45 km² and the city is part of a broader metropolitan and suburban zone that includes neighboring comuni such as Assemini, Capoterra, Elmas, Monserrato, Quartu Sant'Elena, Quartucciu, Selargius and Sestu. The shoreline to the east features the long urban beach of Poetto, while the old town occupies a defensible promontory overlooking the harbor. The climate is a hot-summer Mediterranean type (Csa), with hot, dry summers and mild, wetter winters.

History and urban structure

Cagliari’s history stretches from prehistoric and Phoenician settlements through Roman, Byzantine, Pisan and Aragonese periods to modern Italian unification. The medieval hilltop district known as Castello contains defensive walls, bastions and a cathedral that reflect the city’s long strategic importance. Below the hill are historic neighborhoods like Marina, Stampace and Villanova, each with distinct streetscapes, and a more recent grid of residential and commercial districts that grew in the 19th and 20th centuries.

Economy, transport and institutions

The local economy mixes port activities, services, government administration and tourism. Cagliari’s harbor handles freight and passenger ferries that link Sardinia with mainland Italy and other Mediterranean destinations. Air links operate from the nearby airport. Public transport within the city includes buses and regional rail; the port and airport together sustain much of the island’s external connectivity. The city is also home to higher education and research institutions, most notably the University and various cultural agencies.

Culture, landmarks and events

Cagliari combines archaeological sites, medieval architecture and seaside leisure. Key attractions include:

  • The Castello district with its bastions and panoramic viewpoints;
  • Roman and Phoenician ruins, including an amphitheatre and museum collections;
  • The 13th–14th century towers such as Torre dell'Elefante and Torre di San Pancrazio;
  • National and regional museums that preserve Sardinian art and archaeology;
  • The long urban beach of Poetto, popular with residents and visitors.

Annual religious and civic festivities, most notably the procession for Sant’Efisio, draw large local participation and are important elements of Sardinian cultural life.

Administration and demography

Cagliari is the capital of the Province of Cagliari and serves as the main urban center for the southern portion of the island. The municipal population is on the order of one hundred fifty thousand inhabitants, producing a relatively high urban density (population density). As a regional capital it provides public administration, higher education and cultural services to the surrounding province and the island at large.

History

Karalis or Kalares was a Phoenician colony that later belonged to the Carthaginian Empire and came under Roman rule as a result of the First Punic War (lat. Caralis). During the Second Punic War, the city was the seat of a praetor and the most important Roman naval base in Sardinia. Later, the inhabitants were granted Roman citizenship. In the 4th century, the city was the episcopal see of Lucifer of Calaris. With the decline of the Western RomanEmpire, Cagliari fell into the hands of the Vandals. It then became part of the Byzantine Empire.

In the course of the weakening of the Byzantine rule over the island in the 9th century, five Sardinian Judicates (literally, magistracies) were initially formed. The Judiciary of Cagliari soon annexed the Judiciary of Agugliastra, and for centuries the island was divided into four Judicatories, which is also represented by its coat of arms. During this period of Sardinian independence, however, the city was abandoned by its citizens, as the Phoenician-Roman city, located directly on the sea, was raided several times by Moorish pirates. They founded the new city called Santa Igia further west inland.

With the strengthening of the Italian maritime republics, Pisa and Genoa competed for supremacy over Sardinia. Pisa brought Cagliari under its rule.

In the 14th century, the Pisan territory of Sardinia came into the possession of the Crown of Aragon through Pisa, and thus under Spanish administration through the Treaty of Tordesillas until the 17th century.

After passing from the Spanish to the Austrian Habsburgs for a short time, the Kingdom of Sardinia passed to the House of Savoy in 1718, which established the Kingdom of Sardinia-Piedmont. Thus it has belonged to Italy since 1861.

Places of interest

Dom

The Cathedral of Cagliari, the Cathedral of Santa Maria di Castello, is the Episcopal Church of the Archdiocese of Cagliari and was originally built by the Pisans in the Romanesque-Pisan style from 1217. The church is a conglomeration of numerous alterations and additions, since as early as the 14th century alterations were made, such as the addition of the transept and changes to the façade. During the extensive baroque reconstruction from 1669 onwards, the Spaniards also built the baroque façade in 1702-1704, the remains of which are stored behind the Cathedral Museum. This was demolished in 1903 due to dilapidation and rebuilt in 1933 in the style of the Pisan Romanesque. The Pisan architrave of the main portal and the portals of the transept arms (Pisan to the north, Gothic to the south) are original. Above the lintel of the southern transept portal, the front wall of a Roman sarcophagus is walled in.

The interior of the cathedral is completely rebuilt in Baroque style. In addition to the ornate floor of colored marble, the silver chased and very finely chased tabernacle of 1610 from Palermo and the chased silver anpendium of 1655 from Madrid, the ceiling paintings, sacred sculptures and richly decorated tombs, the altarpiece "Retablo della Crocifissione" with a depiction of the Crucifixion and the enthroned Madonna from 1528/30 and the marble pulpit by the master sculptor Guglielmo, created between 1159 and 1162, are particularly worthy of mention. The latter was originally in Pisa Cathedral and was brought to Cagliari in 1312 as a gift from the Pisans for the Cathedral. The pulpit, cut in two during the Baroque reconstruction and moved to the west wall, with scenes from the life of Jesus, is considered one of the most outstanding works of Pisan art in Sardinia. Master Guillelmus is sometimes equated with Master William of Innsbruck, who is also said to have built the Leaning Tower of Pisa. Four stone lions, which originally supported four of the seven pulpit columns, now flank the stairs and the corners of the presbytery gallery in the crossing.

The crypt is worth mentioning. The vault is decorated with 600 rosettes, no two are alike. It houses burial chambers with the remains of almost 300 Sardinian martyrs who were transferred to the crypt from the church Basilica di San Saturno in the 17th century.

Basilica

The Basilica di Nostra Signora di Bonaria with its imposing baroque façade is a much-visited pilgrimage church and the Sardinian seat of the Mercedarian Order. From the sweeping flight of steps you have a wonderful view of the Golfo degli Angeli. The basilica was named Nostra Signora di Bonaria after a statue of the Madonna which, according to legend, was washed up here on a stormy night in 1370. When the people opened the box containing the figure, they were astonished to find that the candle in the Madonna's hands was still burning. Thus the Madonna became the patron saint of fishermen and sailors and eventually of the island of Sardinia.

Amphitheatre

Anfiteatro Romano dates back to the 2nd century BC and is the largest Roman building in Sardinia, covering about 1150 m². It was built directly into the hillside, the rows of seats are partially carved into the stone and supposedly offered space for up to 20,000 visitors, which was roughly equivalent to the total population of Cagliari at the time. The term "amphitheatre" indicates that the arena could be submerged by means of underground channels in order to perform - in addition to animal and human fights, theatrical performances and the like - the naval combat spectacles that were popular at the time.

The theatre had its heyday during the Roman Empire; later, from the Middle Ages to the period of Spanish rule, it was no longer used and fell into disrepair. In 1866 it was cleaned up and renovated, with additions such as aisles and rows of wooden seats, so that the archaeological site can still be used as a venue today. In the summer, concerts, festivals and musical performances are regularly held against this fantastic backdrop.

Towers

Torre dell'Elefante and Torre di San Pancrazio: Elefante Tower and Pancrazio Tower are part of the Pisan fortifications from the early years of the 14th century, works of the famous architect Giovanni Capula. Under the Spanish, the towers functioned as prisons, the open spaces in front of them supposedly as execution sites. For this purpose, the towers were also walled up on the fourth side and were not restored to their original state until 1906. Finally, in 1999, they were renovated again. Since then they have served as lookout towers.

The name "Elephant Tower" is derived from the small marble elephant above the gate. Why and since when it has been standing there is not clear. A second elephant portrait can be found at the top of the entrance stairs: it is a rough stone relief depicting a somewhat misshapen elephant.

The Torre San Pancrazio takes its name from a small church near the tower.

Bastione di Saint Remy

Popular with tourists and locals, the neoclassical-style square was built in 1901 on top of the old bastion from Piedmontese times as a panoramic terrace and meeting place for the urban population.

The interestingly structured garden shows among other things native plants, medicinal plants, biblical plants, an extensive cactus collection as well as rare plants of the different continents. Furthermore, there are archaeological sites on the grounds, e.g. cisterns and a Roman cave. The park, which is accessible to the disabled, has several water features.
  • The Spiaggia del Poetto, the beach southeast of Cagliari and south of the municipality of Quartu Sant'Elena (with 70,000 inhabitants), is almost seven kilometres long and five to a maximum of twelve kilometres from the centre of the city of Cagliari.
  • The Saline di Quartu, a saline landscape in the Parco naturale regionale Molentargius of the metropolitan area of Cagliari, is located longitudinally between the beach of Poetto and the aforementioned urban settlements. The saline system is still maintained, but salt production ceased in 1984 due to contamination in the irrigation intakes. In this landscape, in times of active cultivation by the people, there was their residence called ''La città del Sale''. It includes a church called: "La chiesa del Santissimo nome di Maria", consecrated in 1934 but abandoned by the Roman Catholic Church in 1979.
