Early Origins and Strategic Location

Before the construction of the fortress, the site was occupied by a hermitage dedicated to Saint Sebastian, highlighting its early religious significance (Ayuntamiento de Vigo). The choice of location was strategic—overlooking Vigo’s bay from a coastal promontory, it provided an ideal vantage point for monitoring maritime activities and defending against seaborne threats.

Construction and Military Role

Timeline and Context:
Construction began in 1656, a period marked by frequent attacks on Vigo from English pirates and Portuguese forces during the Portuguese Restoration War (1640–1668). The fortress was designed to work in tandem with the nearby Fortaleza de O Castro, forming an integrated defensive network (Galicia Máxica; Vigo en Fotos).

Key Contributors:
Military engineers Juan de Villarroel y Prado, Carlos Grunemberg, and Fernando Grunemberg oversaw construction. The defensive wall extended from the Castillo de San Sebastián to the Puerta del Sol, along the city’s historical perimeter (Wikipedia).

Architectural Features and Defensive Design

Structural Elements:

Granite Walls: Thick, load-bearing granite walls were tailored to the rugged coastal terrain, maximizing durability.
Bastions: Projecting bastions provided overlapping fields of fire, a hallmark of early modern military engineering.
Gateways and Tunnels: The main gate controlled access, while subterranean tunnels connected the castle to other city points and possibly to O Castro fortress (Galicia Máxica).
Internal Structures: Barracks, storage rooms, a chapel, and a polvorín (gunpowder magazine) were housed within the fortress (La Voz de Galicia).

Gardens and Views:
The grounds feature meticulously sculpted gardens with benches and winding paths, offering panoramic views of Vigo, its estuary, and the Cíes Islands (Castlepedia).

Historical Conflicts and Evolution

Military Engagements:
The fortress played a critical role in the defense of Vigo during the Portuguese Restoration War, the War of Spanish Succession, and the Peninsular War. Its defiance against sieges, notably the British assault in 1719, underscores its military significance (portugalvisitor.com).

Decline:
Improvements in military technology and repeated bombardments led to the decline of the castle’s defensive role. After the 1813 polvorín explosion, which caused substantial damage, the fortress was progressively repurposed and partially demolished to accommodate urban expansion (Wikipedia).

Restoration and Modern Cultural Significance

Preservation Efforts:
The castle has been the focus of restoration and preservation programs, supported by local and European funds (Ayuntamiento de Vigo). It is protected under Spanish heritage laws.

Cultural Hub:
Today, Castillo de San Sebastián hosts community events, exhibitions, and festivals, contributing to Vigo’s vibrant cultural life. Its gardens and open spaces serve as a tranquil retreat within the city (Castlepedia).

Integration with Vigo’s Urban Development

The castle’s defensive perimeter influenced the layout of present-day streets and neighborhoods, such as Puerta del Sol, Calle Carral, and Berbés district. The juxtaposition of historic walls and modern city hall highlights the ongoing dialogue between Vigo’s past and present (Vigo en Fotos).
