Torre d'Alfons XII, officially renamed Torre de la Ciutat, stands as a robust 1874 fortification built during the Third Carlist War on Girona's defensive perimeter. Constructed on the site of a 1675 watchtower that was destroyed by French forces in 1814, this 19th-century tower represents Bourbon Restoration military engineering. Rising prominently from the landscape, it served as an anti-aircraft position during the Spanish Civil War and later functioned as Girona's municipal water reservoir until the 1960s. The structure exemplifies how historic defensive architecture was adapted and repurposed across centuries, blending military necessity with municipal infrastructure needs while maintaining its distinctive presence on Girona's skyline.
