Industrial port located in the area called "Giorgino", which serves as terminal container.

In 1553 the Spaniards renewed the defensive walls of the city and, among these structures, the Door of the two Lions was created, surmounted by the two heads of the animal that look on the outside of the walls, in Mazzini street.

It is the gateway from the south to the Castello district.

Porta Cristina is an access gate to the Castello district that connects Buoncammino Avenue to Arsenale Square.

It was built according to the model of the Porta Angelica in Rome, and is dedicated to Maria Cristina of Bourbon, wife of King Carlo Felice di Savoia.

In neoclassical style, according to a project by Count Carlo Pilo Boyl, approved by the king. Its lines present the open access arch between two pilasters that support an entablature delimited by two projecting cornices, within which it is placed a semi-circular lunette that has this dedicatory inscription:

“Karolus Felix Rex
viam planiorem brevioremque a Castro Caralis
ad portam arcis regiam aperuit
Maria Cristina Regina
Portae egressus in apertam viam nomen suum imposuit
MDCCCXXV
Januario Rotario regni praeside”

The Museum contains a small section of contemporary art and sculpture as well as oils, coats-of arms, religious objects and paintings. The altarpierces are the most interesting part of the collection. They offer a complete panorama about the best Sardinian school of painting.

The National Gallery of Cagliari, located within the museum complex of the Citadel of Museums, was previously situated on the existing structure of the Royal Arsenal. Then, since the late nineteenth century, it was hosted in the Palace of Seziate in the nearby Piazza Indipendenza, and for more than a century it was closed to the public. It finally found its permanent home in the current headquarters inaugurated in 1992. The National Gallery gathers together, in addition to a small section of contemporary art and sculpture, paintings, coats of arms, ornaments and pictures. The altarpieces are considered the most interesting part of the collection, as they offer a panorama of the best Sardinian paintings from the initial penetration of the Catalan-Valencian flavor in the island to the products of the local workshop of Cavaro and the associate school of Stampace.

The first nucleus of the collection was formed during the nineteenth century, after the abolition of the ecclesiastical authorities in 1866 and the destruction of San Francesco di Stampace church in 1875. In fact, at the beginning of the twentieth century new acquisitions and donations have enriched the Art Gallery with a beautiful and interesting ethnographic collection (fabrics, beautiful Sardinian jewels, furniture, pottery and weapons ). Moreover, from1919, an ewer take part in the collection. It is an extraordinary piece in the form of a volatile, built in the twelfth century by an artist of Byzantine culture. This is a rare piece of bronze sculpture similar in workmanship and decoration, to the exemplary "twin" of the Louvre Museum.

The majestic Saint Remy Bastion houses the Covered Walkway, the city meeting place on the top of its ancient walls.

Inaugurated in 1902 as a banquet hall, throughout the years the walkway has been used for various purposes: an infirmary during the World War I, a complementary school in the 1920s, a branch office for the Treasury and a shelter for the homeless in the second post-war period. Moreover, in 1948 it hosted the first edition of the International Fair of Sardinia.

The space is characterized by wide halls, decorated in bright colors.

The Covered Walkway leads to the Sperone Gallery, a part of the structures built by the architect and military engineer Rocco Cappellino to protect Cagliari from 16th-century Muslim military incursions. Convened by Charles V, Cappellino created the first modern defence project in Sardinia, made up of towers, ramparts, fortified cities and castles.

The Gallery was also built with the aim of embellishing the buildings of the Bastion, which had the front to the sea. Its internal environment is called "vaulted casemate" and it was used for military usage. It also took the name of "Cannoniera" because it placed a cannon whose shot crossed with that of the cannon positioned in the Bastion of the Balice, which is located in University street. This new defensive technique served to protect the “Porta dei Due Leoni”, the entrance to the gallery, which was the only access from the south to the fortified city.

Inside the Gallery there also was an access road that led the condemned to death to Piazza Martiri.

One of the areas was used as a prison. In another room there was, however, a public cistern that distributed water in the Castello area.

An internal part of the gallery was also used as an air-raid shelter during the Second World War.
