Village
San Fernando, known as La Isla, sits on the island of León, in the Bay of Cádiz, beside the Atlantic and separated from the city of Cádiz by the Arillo river; it is part of the Bay of Cádiz-Jerez metropolitan area. With 93,338 inhabitants in 2025 it is the fourth most populous city in the province, in a municipal area of barely 32 km². Inhabited since prehistoric times, it received the Phoenicians, who built the temple of Hercules on the islet of Sancti Petri and introduced salting, and later the Romans, who built an aqueduct over which the Zuazo bridge would later rise. It was born as Villa de la Real Isla de León, founded in 1766, and took its current name in 1813 in homage to Ferdinand VII, who granted it city status for hosting the Cortes de Cádiz between 1810 and 1812.
Monument
The Real Teatro de las Cortes, in San Fernando, was built in the early 19th century, at a time of great demographic and economic growth for the city; formerly known as the Corral or Casa de Comedias, and until 2001 as the Teatro de las Cortes, it is this very building - not an earlier one - where the deputies who drafted the Spanish Constitution of 1812 met, between 24 September 1810 and 20 February 1811, before moving to Cádiz. After years of neglect, it was refurbished and reopened in 1999, when its historical value as a decisive setting for Spanish constitutionalism was recognised. Today it continues to host theatrical performances in the city of Cádiz.
Monument
A scientific research and cultural outreach centre belonging to the Spanish Navy, considered the oldest modern observatory in Spain and one of the most important in the world. It functions as an astronomical and geophysical observatory and as a higher education centre for the scientific personnel of the Navy, and holds a library of 30,000 volumes. The building, one of the finest examples of neoclassical architecture in the Cádiz area, was built at the end of the 18th century on the Torre Alta hill, with great simplicity and purity of line, replacing the earlier headquarters located in Cádiz, whose altitude was insufficient for astronomical observation.
Monument
Castillo de San Romualdo, formerly known as Logar or Lugar de la Puente, Castillo de Suazo and, in Arab times, Alquería de Rayhana, is a ribat - a building of Islamic origin used as a fortress and place of worship - located in San Fernando (Cádiz), next to the Zuazo bridge. Due to its characteristics it is unique in all of Spain; its construction probably predates the 13th century, although doubts remain about the exact date and reason for its building. The present-day city of San Fernando, formerly known as Isla de León, grew up around the old ribat and the Real Carenero, next to the Zuazo bridge. It was declared a historic-artistic monument in 1931 and is today a Bien de Interés Cultural (Spain's highest level of heritage protection) with monument status.
Curiosity
José Monje Cruz, 'Camarón de la Isla' (San Fernando, 5 December 1950 - Badalona, 2 July 1992), one of the most influential singers of contemporary flamenco, was born in the Las Callejuelas neighbourhood of San Fernando, into a Roma family; the nickname was given to him by an uncle because of his thinness and his fair skin and hair, and 'de la Isla' refers to the city's location on the island of León. He left school early to help his father, a blacksmith and amateur singer, and from the age of seven he sang in taverns, ventas and at the local tram station. In 1958 he began performing at the Venta de Vargas in San Fernando, where he was heard by the great singers of the region; at the age of twelve he won the Montilla Festival. He was born and is buried in San Fernando.
Nature
Camposoto beach, also called Castillo beach, is an unspoilt beach in the municipality of San Fernando (Cádiz) that stretches for more than 6 km, of which almost 5 are usable, from Punta del Boquerón to Torregorda, already within the municipality of Cádiz. Part of the Bahía de Cádiz Natural Park, declared in 1989, until a couple of decades ago it was an Army firing range, which has kept it in a semi-wild state; public access was permitted in the 1960s and since the 1980s it has had toilets, beach bars and car parks, receiving the Blue Flag every summer since 2000. In its surroundings, batteries and bunkers from the wars of the 20th century are preserved, today unmaintained, and facing it, on an islet, stands the Castillo de Sancti Petri.
