Cugia Palace, also called Palazzo Nieddu is located at Via Genovesi, next to Siotto Palace. The Neoclassical facade is articulated on two floors and a ground floor.

The coat of arms of the Carroz and Centelles families visible on the large balcony of the first floor of the building shows that the Earl of Quirra (Don Gioacchino Carroz Centelles) lived in this building, after moving from the Castle of San Michele. In the early nineteenth century, the lawyer Pietro Nieddu became its owner and commissioned to the architect Gaetano Cima the renovation of the building, which also included the façade. The owners of the palace succeeded over time, up to the Cugia family.

The Palazzo Civico of Cagliari is the municipal seat of Cagliari. The building is located in Via Roma, in the lower part of the district of Stampace.

The former Town Hall, located in Castello district, was the municipality seat until the end of the nineteenth century. In 1896 the City Council decided to move the Town Hall to via Roma, in the area that overlooks the harbour. The building was inaugurated in 1907.

The losses caused by bombing in 1943, were so serious that it took several years to restore the building to its original appearance. The building, made of limestone, it's a perfect combination of Catalan-Gothic style visible in the porch, and the Art Nouveau of the facade. The main facade has seven arches, in addition to the central one, nine metres high, through which we reach the inner courtyard of the palace. The facade is completed by two octagonal turrets, thirty-eight metres high, while in the corners of the building stand out four obelisks, decorated with the carved heads of “Quattro Mori”. The facade is adorned with various bronze sculptures including an eagle, placed in support of the emblem of the city, two lions on the main facade and the works that symbolize the Agriculture, the Trade and the Industry.

In the “Sala Consiliare” (Council Room) there are three huge paintings by Filippo Figari, made between 1916 and 1924, respectively representing the vicar of Pisa with the Archbishop of Cagliari, Vittorio Amedeo II of Savoy and a group of kneeling Moors. The “Sala della Giunta” hosts some paintings by Marghinotti and a retablo of the councilmen by Pietro Cavaro. The “Sala dei Matrimoni” (Weddings Room) houses a painting by Figari. In this room, inside glass cases, there are jewels, archaeological finds and the seventeenth-century statue representing St. Augustine. The “Sala del Sindaco” (Mayor Room) hosts a large Flemish tapestry, made in 1620 by Franciscus Spierink. Finally, in the “Sala Sabauda” (Savoy Room), there are three paintings by Marghinotti: two official portraits of Carlo Alberto and Vittorio Emanuele II, while the third shows the arrival of Carlo Alberto in Cagliari in 1840.

The building is located between the De Candia Palace and the Teatro Civico. It was built in 1622 by Antonio Brondo Count of Serramanna.

In 1670 the Zapata family acquired the ownership of the building as a result of a marriage between two members of the families Zapata and Brondo. The doorway that opens on Piazza Lamarmora is dominated by a gable bearing the coat of arms of the Marquis of Villacidro, Francesco Lussorio Brondo and a marble plate dedicated to Antonio Brondo.

Boyl Palace is one of the most representative noble buildings of the district of Castello. It was erected in 1840 by Carlo Boyl Pilo, Marquis of Putifigari.

The building was designed in the neoclassical style, along the lines of Porta Cristina and of the Royal military arsenal's main entrance, these also designed by the Marquis of Putifigari.

The building consists of a marble parapet adorned by four statues representing the Seasons, in the central part the gentle coat of arms of the House is carved. Below the inscription that reminds the year when the building was erected: "COMES KAROLUS PILO BOYL EX MARCHIO PUTIFIGARI INSTAURAVIT ANNO MDCCCXL".

A Pisan tower, which served as access to Castello district and was contemporary with those of San Pancrazio and Elephant, was absorbed by the building. The tower suffered three devastating attacks: the British in 1708, the Spanish siege of 1717, when it lost its upper part and the French attack in 1793. Three cannonballs stuck on the façade of the building are a vivid testimony of the three attacks suffered. Beyond the gate, on the left side, you can see a Roman funeral stele, which had been walled up in the tower along with other inscriptions. At the end of the nineteenth century, the palace was acquired by the Barons Rossi's family. The current owners are the Earls from Marche, Tomassini Barbarossa.

The building is located along Viale Trieste on the corner of Via XXIX Novembre. It was planned by Riccardo Simonetti, and made definitely in 1921.

The combination of Liberty elements with the Renaissance’s style, the refinement and the attention to details make this palace a unique work. The corner of the building is particularly remarkable, by superimposing the bow window on each floor. The two façades show openings and balconies which are totally different in the three floors, but they are all richly decorated with an ornament that combines concrete, iron and terracotta.

The building dating back to the second half of the nineteenth century, rises in an area which includes Piazza Santa croce, Via Corte d'Appello and Via Santa Croce.

The main façade, in Neoclassical style, overlooks the Bastion of Santa Croce and develops into four floors. The second and third floors show windows decorated with blind gables and wide cornices, and balconies with wrought iron railings; in deep contrast to the previous ones, the windows on the first and fourth floors appear austere and unadorned. A marble headstone, dating back 1630 and placed at the entrance of the first floor, recalls the existence of a fountain located at Piazza Santa Croce, later incorporated into the building. The Azara palace during the years following its construction was used both as a municipal seat and as a museum, to keep the paintings from the church of Santa Teresa and from the disappeared church of San Francesco.

The building is located at Via Canelles in the historic district of Castello. Built during the Middle Ages, it has undergone several renovations until reaching its present appearance in the Art Nouveau style.

It has two floors, in addition to the ground floor, characterized by partition cornices and six paired windows on each floor. On the ground floor of the main façade we find the particular smooth rustication, typical of the buildings designed by Gaetano Cima. Each opening with a balcony is adorned with graceful terracotta tiles and with elegant spiral mullions. The windows on the first floor, overlooking via Canelles and vico Lamarmora, are adorned with decorated cornices.

The entrance hall's stairwell is particularly interesting, with two symmetrical flights of stairs, with mullion handrails, leading to a landing from which a secondary flight of stairs gives access to the apartments.

The building, erected in the second half of the eighteenth century is located at Via Lamarmora, overlooking the Piazza Carlo Alberto.

Following the bombings of 1943 the building was severely damaged and, after the World War II, it was carefully restored. The building, built according to the taste of “Piedmontese Barocchetto”, is on two upper floors, a mezzanine floor and a ground floor. The windows are different according to the floor: those of the middle floor have balconies flush with the façade and are unadorned; the windows of the upper floors have protruding balconies and wrought iron railings. The main entrance is characterized by Doric pillars and it's dominated by a triangular gable in which the gentle shield of the owners (Nin of St. Thomas) is carved.

The building, is home and residence of the Archbishop of Cagliari from the XII century.

It is situated in an area of Castello district, where also other typical buildings of Cagliari's history (the Cathedral, the Royal Palace, the former Town Hall) are located. Carlo Felice lived there during the Napoleonic period, because of the inadequacy of the Royal Palace. The current appearance of the main façade is due to significant reconstruction works, which took place at the end of the third decade of the last century. On the side wall funerary inscriptions are visible, dating back to the first Christian era. In the inner rooms numerous paintings and archaeological finds are kept; you can also see part of the original structure of the Cathedral, in Romanesque style.

The building is located in Via Lamarmora between La Purissima Church and the former headquarters of the Archaeological Museum. Made in the eighteenth century it was owned by Masones family.

In the nineteenth century, two  important events changed the history of this building: the Marquis Fancesco Amat purchased the palace, modernising and expanding it. The building has two facades: one gives onto Via Lamarmora and the other on Piazza Indipendenza. The facade on Via Lamarmora spread over two floors with a succession of wrought iron balconies. The main entrance leads to a large hall whose ceiling is decorated with the coat of arms of the Amat family.
