CASTLES SAN FERNANDO

Castillo de San Romualdo in San Fernando, Cádiz, is a medieval fortress built in Mudéjar style during the second half of the 13th century, featuring a quadrangular plan with a central courtyard and corner towers. Originally part of a strategic defensive line along the Atlantic coast protecting Seville, the castle gained additional historical prominence when it served as the seat of the Council of Regency during Spain's War of Independence in 1810, hosting the Cortes and functioning as government offices, troop barracks, and hospital. Protected as a Bien de Interés Cultural monument, the fortress represents both the military engineering and political significance of medieval Andalusian fortifications.

Batería de Urrutia is an 18th-century coastal defense fortification located at Punta del Boquerón in San Fernando, Cádiz, within the protected Cádiz Bay Natural Park. Named after General José de Urrutia, founder of Spain's Military Engineering Corps, the battery was constructed to defend the entrance to San Fernando Bay through the Caño de Sancti-Petri channel. Part of an integrated defensive system protecting the Sancti-Petri settlement alongside other batteries and the historic Castillo de Sancti-Petri, the structure played a significant role in 19th-century Spanish political upheavals, particularly during the 1823 campaign supporting King Ferdinand VII. Today, the fort remains partially overgrown with vegetation, its military courtyard and guard quarters still discernible amid the natural landscape.
