The Castillo de San Diego once stood as a formidable bastion defending A Coruña’s Atlantic harbor, serving as a crucial node in the city’s coastal defense system alongside the Castillo de San Antón and Castillo de Santa Cruz. Built in the early 17th century atop a tidal peninsula shaped by the Monelos River estuary, the fortress not only protected A Coruña from pirates and foreign fleets but also contributed to the city’s maritime identity. Although demolished in 1963 to accommodate port expansion, the legacy of Castillo de San Diego lives on through local advocacy, historical memory, and ongoing proposals for commemoration and ecological restoration.
This guide delves into the historical and architectural significance of Castillo de San Diego, provides up-to-date visitor information for the site and related landmarks, and offers practical advice for exploring A Coruña’s rich coastal heritage.

Early Origins and Strategic Purpose
Constructed in the early 17th century, the Castillo de San Diego was strategically positioned to defend A Coruña’s port, forming an integrated defense system with the Castillo de San Antón and Castillo de Santa Cruz. Its design reflected the military innovations of its time, with thick stone walls, angular bastions, and advanced artillery positions to deter attacks from sea and land (La Opinión A Coruña).
The Monelos Estuary and Environmental Context
The fortress originally stood atop a tidal peninsula defined by the Monelos River estuary and surrounded by vibrant marshes (xunqueiras). The area’s dynamic ecosystem supported local livelihoods, with tidal mills operating until the late 19th century and women gathering at the riverbanks for washing (La Opinión A Coruña). Over time, port expansion and land reclamation dramatically reshaped the coastline and buried the river’s channel.
Evolution, Decline, and Destruction
A Coruña’s transformation into a modern port city in the 19th and 20th centuries diminished the military relevance of Castillo de San Diego. In 1963, the castle was demolished to facilitate further port development, erasing its physical presence from the landscape (La Voz de Galicia). Today, the former site is part of an industrial port zone, with only street names and local memory hinting at its historical role (La Opinión A Coruña).
Cultural and Historical Significance
Despite its demolition, the Castillo de San Diego remains a potent symbol of A Coruña’s maritime and military history. The fortress, together with the surviving Castillo de San Antón, represents the city’s resilience and strategic importance. Local organizations such as Grupo Naturalista Hábitat and Asociación Veciñal Oza-Gaiteira-Os Castros continue to advocate for recognition and possible reconstruction of the site (La Opinión A Coruña).
Modern Proposals for Restoration and Commemoration
Recent proposals encourage partial removal of port landfill to restore the original estuary and tidal habitats, and even consider reconstructing Castillo de San Diego using modern archaeological methods. These initiatives aim to blend cultural preservation with environmental resilience, potentially creating a new ecological and educational landmark for A Coruña (La Opinión A Coruña).
