The church was built in the XVII century, on the premises close to the main house of Ballero family , forming a single complex. It has an octagonal dome finely decorated , and a simple façade with a belfry in which is located the bell, date back to 1679. In the inside, it is housed a shrine of the 18th century and a hand-painted majolica floor. Inside the dome there is a fresco of the four died, probably date back to the time of Eleanor of Arborea, characterized by the fact that all the Moors look in a different direction and have their eyes blindfolded. Above the altar, we find a painting of the 18th in gold leaf, a wood and plaster cross and a statue of Saint Ephisius from the same period.

The Church is dedicated to Saint'Avendrace, fifth bishop of the city. The building is located on the site where , according to the tradition, the saint was martyred. The facade is simple, with a portal surmounted by a rectangular window and a bell tower. Inside there is a single nave with pointed arches and side chapels covered by barrel vaults.

The church stands on a small subterranean environment, of rectangular form, which is accessible through a trap door in the floor near the entrance. Tradition has it that this was the cave where the bishop Avendrace tried to hide himself during persecutions , and where he was buried after his death in 87 AD .The roofing has a vaulted ceiling, and close to a wall there is a holy well believed to be miraculous.

Throughout its history, the Church underwent some renovation works and changes which make difficult to define the original dating . Furthermore, the first church was oriented in a different way, with the apse located at the point where now lies the entrance , so that the crypt was just below the altar. This fact leads us to believe that the temple was built in honor of the burial place of the saint. The crypt was modified after the restructuring in1952; it was covered with a layer of concrete for protection , causing a significant decrease in the volume and changing the original appearance.

The church, that was built in the eighteenth century, is located in via Manno, inside Marina district, over a chapel of a preexisting hospital, which during the past, was part of a convent.

On the outside, the temple is characterized by a façade with a big portal, above which there is an elaborate niche containing the statue of the saint.

The interior has an octagonal plan and six side chapels with barrel vault; the decoration is in late Baroque style, with green plasters on which stand golden stuccos. In the chancel, there is a polychrome marble altar, decorated with golden stucco too.

The Church of St. Anna is a Baroque church, located in the heart of the Stampace district, in the same place where originally there was a small temple, dating back to Pisan period. The restoration lasted approximately 33 years, mainly dued to a lack of capital.
The impressive structure is characterized by a wonderful staircase. The structure of the church is a typical exemple of Piedmontese Baroque architecture. It features two bell towers three domes of different size and height.
The interior has a single nave, very large and bright, surrounded by four side chapels. It is possible to admire a beautiful polychrome marble altar and the main altar which houses a marble statue of St. Anna.
The building was damaged and partially destroyed by the bombs during the Second World War. lt was later restored and reopened to the public in 1951.

Four pilasters divide the facade into three main parts: the central one with the arc-shaped entrance , on which stands a belfry. On both sides of the facade there are small ascending arcs that end above the entrance. The origin of the name is taken from the diminutive of Alenixedda, Aleni, that is Elena in Sardinia, mother of Emperor Constantine, who was celebrated as a true saint in the island.

The diminutive was created with the intent to distinguish two churches completely different to each other, but devoted to the same saint: the first one, which was erected on the site of S. Vetrano, and the larger one, built in the adjacent town of Quartu Sant'Elena.

The monumental church of St. Augustine was erected around 1577, in the Marina district, using a Renaissance style. Originally, the temple was built in an other location, where now it is possible to find Largo Carlo Felice street and where  St. Augustine's crypt still exists. Here, between 504 and 722  A.D, the Saint's remains were kept. They were brought from Africa,by the monk Fulgenzio, in order to save them from Vandals.

The main entrance is located in Baylle street, but there is a secondary entry connected with Largo Carlo Felice, which introduce to the vestry's yard.

The building has a Greek cross plan, with barrel vaults; at the conjunction among the four arms , there is a semispherical dome. Among the internal  furnitures stand out different pictures, a golden and  wooden altar in Baroque style and  the simulacrum of St. Augustine.

The current church was built in 1950, after the restoration of a previous large chapel  that was destroyed during the bombing in the Second World War.

The new building is neo-Romanesque-Pisan  style and presents a façade in brick masonry clad in limestone. In the central part  is possible to see a cusp, with a central circular window, framed by sculptural decorations.

Above the main entrance there is a lunette mosaic, dedicated to the Saint.

The interior has a Latin cross plan , and is characterized by simple and essential design elements.  Inside, there are three naves; the central one is taller and wider than the aisles, separated by columns partition.

St Simone's church is located in Sa Illetta, near Santa Gilla's pond, and dates back 16th -17th century. Not very big,the church presents a simple facade,with a big and precious portal,and, in the middle, a  small bell. The building is encased in a privately owned farm,and every year, on  the 28 of October,  is celebrated a procession, during which the fishermen of Santa Gilla sail with typical ships, in order to honour the Saint.

St Sebastiano's church is a huge building,built in a modern style and charachterised by squared shapes.
The entrance is slightly recessed from the front of the facade and has two doors with colored inlays. At the top stands a simple cross, but the most characteristic feature of the church is an impressive and unusual bell tower, located in the square in front of the temple ; it is formed by three columns that rise up till  join themselves. In that  point is placed a frame square that houses the bells.

The Church of Saint Pio X overlooks via della Pineta. The façade is simple, covered in large part by red bricks and, in axis with the portal, a stained glass window in the shape of a Latin semicross stands out. The rectangular bell tower is characterized by duotone. The parish was erected by the will of Monsignor Paolo Botto in the late 1950s and was part of the pastoral plan of spiritual assistance, aimed at the city devastated by the bombings of 1943, and which started after the end of the Second World War.
