History And Construction Of The Bordeaux Submarine Base

Building Process


In the ominous early years of World War II, the high command of both Italy and Germany convened a monumental decision. Their shared vision was to fortify the Atlantic coast with an invincible bastion for their lethal submarine fleet – right in the heart of Bordeaux. Construction commenced in 1941, with German engineers meticulously carving out the blueprints of what would become an indomitable piece of war architecture.

The Bordeaux Submarine Base, a monolithic testament to wartime prowess, sprawls across 42,000 square meters. It was conceived as one of five such citadels the Germans sculpted along the Atlantic coast, fortresses that would shelter their menacing U-boats.

Boasting a formidable design that eclipses most World War II architecture, the submarine base is an embodiment of both functional simplicity and architectural complexity. It houses 11 alveoli (bays), interconnected through a labyrinthine inner street, standing as a silent testament to the strategic maneuvers of war. This colossal structure, reaching for the sky at 20 meters high, was an audacious feat of engineering prowess.

This historic marvel was designed to resist even the most severe bombing raids. Its purpose was clear – to create an impregnable sanctuary for the submarines, a safe haven where they could lick their wounds and strike back. The Bordeaux Submarine Base serves as an eerie reminder of the immensity of war and the human capacity to create such awe-inspiring, yet destructive, monuments.

World War II Role

In the tempestuous year of 1940, Italy’s Admiral Angelo Parona, accompanied by his staff, graced the freshly minted Bordeaux Submarine Base. With a ceremonial flourish, he christened it “Betasom,” an amalgamation of ‘Beta,’ the Greek analogue for Bordeaux, and ‘Som,’ the Italian abbreviation for submarines. This fortified enclave, a sentinel on the Atlantic, became a linchpin in the combined German-Italian submarine operations during World War II, vigilantly patrolling a crucial sector south of Lisbon.

Now, armed with an understanding of the Bordeaux Submarine Base’s historical gravitas, let me regale you with tales of its present-day charisma that make it a must-visit.

Post-War Uses Of The Bordeaux Submarine Base

Cold War Period

In the aftermath of World War II, the Base de submarinos de Burdeos saw a shift in its purpose. Its days as a military stronghold, a hulking sentinel of the Atlantic coast, seemed to be consigned to history. Yet, as the embers of one global conflict cooled, another was igniting — the Cold War. In this era of tense standoffs and veiled threats, the base’s purpose was redefined, not extinguished.

The base’s imposing bunker, a formidable expanse of concrete and steel, found newfound value in this volatile geopolitical climate. Its sturdy construction, designed to withstand the wrath of World War II bombardments, was capable of offering significant protection against potential nuclear threats. The base thus evolved from a proactive weapon of war to a defensive shield, a potential sanctuary in the event of Cold War escalation.

The legacy of this transition is evident even today. During your visit, take note of the thick, hardened structure of the bunker, designed to resist and survive. Reflect on its purpose as a safe harbor amidst the threat of nuclear conflict. While the base no longer serves a military function, it stands as a testament to the measures humanity has taken to safeguard against the unthinkable.

The Base de submarinos de Burdeos is thus a tale of two periods — its birth during World War II and its survival during the Cold War. A visit provides a fascinating look at a lesser-known aspect of 20th-century history, further enriching the base’s already compelling narrative.
