The Fort of São João Baptista da Foz, standing at the mouth of the Douro River in Porto, was constructed during the period of the Iberian Union (1580-1640). This union emerged when Portugal, after the death of King Sebastian I without an heir, came under the rule of Spain’s Philip II. While this union provided temporary stability, it also brought new threats from Portugal's European rivals—especially England, the Netherlands, and France.
At this time, Europe was in a state of geopolitical tension. As Spain engaged in prolonged wars with Protestant nations, Portugal, now aligned with Spain, became a target. England, under Queen Elizabeth I, conducted daring raids on Spanish and Portuguese territories, with figures like Sir Francis Drake making their names by attacking Iberian assets across the world. Meanwhile, the Dutch, fighting for their independence from Spain, sought to disrupt Portugal's lucrative trade routes and seize its colonies.
Fearing these threats, Philip II initiated a massive coastal defense project, which included the construction of the Fort of São João Baptista da Foz. Its purpose was to protect Porto’s strategic harbor and safeguard the city from potential naval invasions by England and the Netherlands. The choice of naming the fort after Saint John the Baptist reflects the sense of impending danger at the time, with the saint called upon to protect this critical fortification.
However, fate had a different plan for the fort. Though built to defend against foreign powers, it never faced the full-scale assaults it was designed to repel. Despite the looming danger from England and the Dutch, Porto was never directly attacked by these fleets.
Yet, the fort would later prove crucial during Portugal's internal conflicts. During the Liberal Wars (1828–1834), a civil war between supporters of absolutism and liberalism, the fort played a key role in the defense of Porto. Liberal forces, led by Pedro IV, sought to defend the city from the armies of his brother Miguel, an absolutist who aimed to seize the throne. During the Siege of Porto (1832–1833), the fort safeguarded the sea routes, allowing the liberals to receive reinforcements and supplies by sea.
This siege became a decisive moment in Portugal's history. Pedro IV fought to secure the throne for his daughter, Maria II, and establish liberal reforms in the country. Thanks to the fort and its strategic position, Porto withstood the assault, and the liberals eventually triumphed, setting Portugal on a path toward constitutional governance.
Thus, the Fort of São João Baptista da Foz, initially constructed to defend against external enemies, found its true significance in shaping the internal struggles and political future of Portugal.
