2. The History of Castillo San Felipe de Barajas
Origins: A Fortress Born of Fear and Power
The need for fortification became apparent shortly after Spanish conquistador Pedro de Heredia founded Cartagena in 1533. As Spain’s dominance in the New World grew, so did the envy of rival European powers. The city soon became a major port for gold, silver, and enslaved people, turning it into a lucrative target for corsairs and pirates, including the infamous Francis Drake.
To defend the city and its treasures, the Spanish built the original fortress in 1536, strategically positioned on the San Lázaro hill. From this elevated position, the Spanish could monitor all land and sea approaches to Cartagena.
Evolution Through the Centuries
Recognizing the growing threat from naval superpowers like England and France, the Spanish crown ordered major expansions in the 17th and 18th centuries. The most significant works were carried out in 1657 and later in 1762, transforming the castle into the most robust fortress in Spanish America.
During this period, hundreds of enslaved African laborers were forced to construct the massive walls and subterranean networks, leaving behind not only an architectural legacy but a deeply human one filled with resilience and pain.
The Unforgettable Battle of Cartagena (1741)
Perhaps the most remarkable episode in the fortress’s history is the Battle of Cartagena de Indias. In 1741, British Admiral Edward Vernon launched an enormous assault with over 180 ships and 23,000 men, intending to seize Cartagena and break Spain’s hold on the Caribbean.
Defending the city was Blas de Lezo, a Spanish admiral with a legendary reputation despite having lost an arm, a leg, and an eye in previous battles. With just 3,600 men, Lezo masterfully used the fortress’s defenses, narrow tunnels, and elevated positions to resist the siege.
After over two months of intense fighting, disease, and dwindling supplies, the British forces retreated in defeat—cementing Castillo San Felipe’s place in military history as an unconquered stronghold.
3. Architecture & Design
“The Gibraltar of the Indies”
Castillo San Felipe de Barajas was designed purely for military efficiency, unlike many castles built for nobility or elegance. Its form follows its deadly function—every wall, passage, and parapet crafted with defense in mind. Nicknamed the “Gibraltar of the Indies,” its thick walls were constructed using coral stone and brick to absorb cannon fire without cracking.
Ingenious Features
• Bastions and Batteries: Designed to deliver crossfire from multiple angles, covering blind spots and preventing enemy advancement.
• Zigzagging Ramps: Created to slow enemy troops while allowing defenders to shoot down from higher levels.
• Lookout Posts & Guard Towers: Offering panoramic surveillance of the bay and the surrounding terrain.
• Dry Moats: Acting as physical and psychological deterrents to scaling the walls.
The Legendary Tunnel System
Arguably, the fortress’s most intriguing aspect is its labyrinthine tunnel system. These underground corridors were not just for escape but served multiple military purposes:
• Acoustic Advantage: Built to echo footsteps and sounds, helping soldiers detect enemy intrusions.
• Trap Design: Some tunnels were intentionally built with dead ends or designed to collapse on enemies.
• Secret Communication: Allowed movement of troops, weapons, and supplies without exposure to enemy fire.
Today, visitors can walk through these shadowy tunnels and experience the eerie acoustics that once played a vital role in the castle’s defense.
4. Myths & Legends
The Phantom Admiral
According to local lore, Admiral Blas de Lezo, Cartagena’s one-eyed, one-armed, and one-legged hero, still haunts the fortress. On foggy mornings, some claim to hear phantom commands in Spanish echoing through the tunnels, especially near the central battery where Lezo once commanded.
The Lost Treasures of Cartagena
Whispers persist that hidden chambers deep within the fortress contain unrecovered Spanish treasures—gold, jewels, and documents buried during sieges. While archaeologists haven’t confirmed these tales, the fortress continues to captivate the imagination of treasure hunters and historians alike.
Haunted Walls and Echoes
Visitors often report hearing mysterious sounds in the tunnels, from echoing footsteps to muffled whispers. These phenomena enhance the fortress’s already powerful aura, whether due to architectural acoustics or something more supernatural.
