The Church of Saint Bartolomeo is located in the homonymous square and was erected in the 17th century inspired by the canons of the Catalan Gothic style. It hosted the seat of the Beccai, the butchers. The simple gabled façade culminates with a bell tower while the portal was remodeled in the 18th century in the Piedmontese Baroque style. Inside the only nave is surrounded by some lateral chapels among which the one dedicated to the Madonna of Trapani stands out, whose construction is due to the legacy of a noblewoman of Sicilian origins. A sumptuous baroque altar is embellished by the seventeenth-century statue of the Virgin venerated in Trapani.

The Church of Our Lady of Fatima is located in Giorgino, the famous fishing village of Cagliari.

The Church of Our Lady of Hope is located in the heart of Castello district, next to the Cathedral of Santa Maria. It was built as a noble chapel of the Aymerich family, the Marquises of Laconi who lived in a nearby building, destroyed by the bombings of 1943. In 1535, on the occasion of his visit to Cagliari, King Charles V granted the coat of arms of the eagle to the noble family, represented on the façade.

The Church of Our Lady of Mount Carmel, originally built in 1580, was completely rebuilt in the 1950s in a Pisan Romanesque style due to the damages sustained during the Second World War, in 1943. The church has a single nave with side chapels, it has a barrel vault surmounted by a dome and is decorated with stupendous mosaics: the one that decorates the apse (made by the artist Aligi Sassu) is enormous and beautiful and it represents the story of Carmel, with the imposing figure of the Prophet Elijah in the centre. The main altar is in marble, the bell tower is surmounted by a bronze statue of the Madonna and in the central chapel, dedicated to the Virgin, a beautiful wooden statue of the Blessed Virgin Mary of Mount Carmel, which dates back to the eleventh century, is still visible. According to the legend, this statue was taken from Mount Carmel in Rome and donated to a member of the Ripoli family from Neoneli. On his journey to Cagliari, this member of the Ripoli family survived a terrible storm and he decided to build a chapel in honor of the Madonna as a way of saying thanks to the Virgin for saving his life. In centre of Piazza del Carmine, the main square near the church, there is an imposing statue of the Madonna of Mount Carmel, whose feast is celebrated on July 16th.

The load-bearing structure made of blocks and with massive stone blocks, is decorated from a large rose window with stained glass, the work of glass artists from Germany.

The Church of Our Lady of the Annunciation stands on the corner of Corso Vittorio Emanuele and Viale Merello. The exact date of construction is not known, but it certainly already existed in 1535 when King Charles V, on the occasion of his visit to Cagliari, granted the coat of arms of the eagle visible on the facade.

The building was built in the seventeenth century, on the site of a small country church destroyed by a storm in 1643. Entitled to the Virgin Annunciation since 1645, it was entrusted to the Piarist fathers, who remained inside it until 1866, the year in which the church was closed for worship and the adjacent convent transformed into a police station.

The Purissima Church was built in the Catalan-Gothic style in the 16th century, along with the nearby monastery. It consists of one nave, divided into two spans with cross vaults, and six chapels with stellar vaults.

The Purissima Church overlooks via La Marmora, in the Castello district and was probably built after 1540 when the noblewoman Gerolama Rams Dessena wanted the construction of a cloistered monastery for the Clarisse. The interior of the building reflects the canons of the Catalan Gothic language: there is a single nave divided by a pointed arch and two cross-vaulted spans, with a pendulous gem in the center. The church was then acquired in the nineteenth century by the state following the law that established the suppression of religious orders and was used as a school.

Built since 1953, the Church of the Miraculous Medal is located in the large San Michele square. The structure, imposing and modern, was made of reinforced concrete with an external coating in stone blocks. The facade is preceded by a porticoed atrium. The building is dominated by a majestic hexagonal dome, at the apex of which there is a large golden statue of the Madonna. Its name derives from the medal, later defined "miraculous", made following the Marian apparitions had by Santa Caterina Labouré in 1830.
