Perched atop the promontory of Old San Juan, the imposing Castillo San Felipe Del Morro stands as an enduring sentinel, its formidable walls a testament to Puerto Rico’s resilient spirit. Affectionately known as “El Morro,” this awe-inspiring fortification has safeguarded the island’s shores for nearly five centuries, withstanding the relentless onslaught of invaders and the merciless ravages of time.

An Architectural Marvel Forged by Necessity

The origins of this colossal citadel can be traced back to 1539, when the Spanish Crown, keenly aware of Puerto Rico’s strategic location, commenced its construction. Nestled at the entrance to the San Juan Bay, El Morro was envisioned as an impregnable bulwark, designed to protect the island’s burgeoning colonial settlement from the ever-present threat of marauding pirates and hostile naval powers.

Its imposing walls, some towering as high as 40 feet and spanning over 20 feet in width, were meticulously engineered to withstand the most formidable of assaults.

A Crucible of Valor: Battles Etched in Stone

El Morro’s storied past is inextricably interwoven with the annals of Puerto Rican bravery and resilience. Its impenetrable ramparts have borne witness to countless skirmishes, each one a testament to the indomitable spirit of the island’s defenders.

In 1595, the formidable Sir Francis Drake, the renowned English privateer, launched a daring attack on San Juan with a fleet of 27 vessels and over 2,500 men. However, the Spanish forces, bolstered by the fortress’s impregnable defenses, resolutely repelled the onslaught, inflicting a humiliating defeat upon Drake’s armada.

The Dutch, too, harbored ambitions of conquering the island, laying siege to San Juan for 21 days in 1625. Yet, as their ammunition and supplies dwindled, they were forced to retreat, leaving the city in smoldering ruins as a parting gift.
