Zuazo Bridge, of Roman origin and built in ostionera stone, was part of the Gades Aqueduct that transported water from Tempul to what is now Cádiz. Its strategic location, since it connects San Fernando with the rest of the province, except for the Sancti Petri tributary and Cádiz by calle Real, meant that it sustained constant assaults and attacks. This is why it is a symbol of the city, as shown in its coat of arms.
A series of defensive batteries protect the bridge which is also situated next to the Real Carenero, the old prop and rigging factory, supplies storage and dry pit installation.
It owes its name to the holder of the nobility title in the 15th century, who was the Judge of the Royal Council, Juan Sánchez de Suazo, who obtained the concession thanks to King John II of Castilla.
The current bridge was the work of the French engineer Louis Gautier who resided on the island.
Throughout history, the Island and Cádiz had to repel different attacks from the English, Dutch, Portuguese and French.
During the War of Independence, the bridge played a very important role, since the French assault commanded by Marshall Victor (Claude-Victor Perrin) Duque de Belluno during the Battle of Portazgo was foiled. So, room was made on the Isla de León and Cádiz with an army of 40,000 men, which lasted for two and a half years. And in 1812, the bridge’s central arch was destroyed to prevent the passage of the French, who retreated since it was impossible to cross the tributary. The bridge concentrated a large number of defensive batteries under the command of Captain Diego de Alvear.
Since 1996 it has been a Cultural Heritage Site.
Due to the population increase experienced in Villa de la Real Isla de León, construction on this temple began in 1756. The original design was done by the architect Alejandro Perdía, slightly modified by a French engineer and completed by Torcuato J. Benjumeda. Baroque in style in the first body and Neoclassical in its towers, this place bore witness to an important historic event which was depicted by the painter José Casado del Alisal in a painting that decorates the east wall of the floor of the Congress of Deputies in Madrid.
Dating back to 1733, it is the oldest religious building preserved in the city. Here is venerated the Virgen del Carmen, patron saint of the city and the Navy. It was the scene of some sessions of the Cortes de Cádiz and in its enclosure was granted to the then Villa de la Real Isla de León, the current name of San Fernando and the title of City in the year 1813, in recognition of its work during the War of Independence and its constitutional role.
The Royal Institute and Observatory of the Navy in San Fernando is an important scientific center and the oldest observatory in Spain. Its origins date back to the 18th century. It is located on the hill of Torre Alta and is an important example of neoclassical architecture. It is here where the official time of Spain is established.
At the mouth of the channel of the same name is the island of Sancti Petri. Sources of Classical Antiquity place in this area the famous temple of Melkart, a divinity of Phoenician origin that links with the cult of Hercules (Rome) and Heracles (Greece). The current fortress was built in the 18th century. It is a magical place of great beauty where the Cultural, Historical, Natural and Landscape Heritage are combined.
The existence of the Real Carenero shipyard was the background to the conception of the construction of this 18th century industrial enclave. This led to the repair duties performed by that enclosure being transferred and expanded with the creation of the new La Carraca Naval Station. The enclosure’s initial plans date from 1720, its layout being very organic and functional. Years later, the main gate of the wharf, the dry pit, the Battalion Barracks and the Penal de las Cuatro Torres prison were all built, with the other buildings completed in the late 18th century, that is, the General Warehouse Gate, the New Church and the Puerta de Tierra, all pure Neoclassical in style.
Although it is difficult to date it. Diverse investigations place the origin of the San Romualdo Castle in the 13th century. It is inserted in the line of medieval fortifications Cadiz of the Atlantic coast along with the castles of Rota and El Puerto de Santa Maria. In 1931 it was declared a National Historic Monument.
Inaugurated in 1804, it is a building of great historic and artistic value. In September 1810, it housed the first sessions of the Cortes Generales and Cortes Extraordinarias of the Parliament that gave rise to the first Spanish Constitution, for which its interior underwent a renovation. This building, declared a Constitutional Monument, has since then had several uses. It boasts the Royal title and was declared a Historic Monument in 1935.
The privileged geographic location of Isla de León on the coast made this a more or less stable settlement site of man since very faraway times. This led to the exploitation of marine resources, especially for conserved and salted goods. This conservation industry created another auxiliary one: the pottery maker, necessary to manufacture the containers (the pots). The Phoenician and Punic furnaces are exhibited in the rotunda of the same name and constitute an exceptional complex in the west, both for the high number of production structures excavated and for their state of preservation. In it, the remains of two important pottery workshops related to the city of Gadir are exhibited: the Late-Punic pottery of Alta Tower and the Phoenician furnaces of Camposoto Sector III.
During the War of Independence this place plays an important historical role being the seat of the Council of Regency of Spain, which convenes the Cortes in September 1810. For this reason, the Religious Sisters were transferred to Cadiz, adapting these facilities for state offices, troop lodging and hospital. This educational center, established in 1760, continues to perform educational functions today.
The building boasts being the largest Town Hall in Andalusia and the third largest in Spain. Its construction work began with the architect Torcuato Cayón in the mid-18th century, but continued up to the 19th century, so there were several architects who left their imprint on the building, enabling us to discover and enjoy the different styles we find in its interior.
