What secrets lie hidden beneath our feet? Here, before us, stand the remnants of the Muralha Fernandina. This impressive wall once encircled Lisbon, a testament to a time of conflict and fear. In 1373, King Ferdinand I, locked in a power struggle with Castile, ordered its construction. The king knew that Lisbon, vulnerable after Castilian attacks, needed a strong defense against future threats.
The Muralha Fernandina, completed in a remarkably short two years, was a marvel of medieval engineering. Imagine, if you will, a wall so extensive that its stone, if reconstructed, could stretch from Lisbon to Porto! This mighty bulwark boasted 77 towers, each around 15 meters high, and 38 gates, all strategically placed to repel invaders. The construction itself reveals a fascinating aspect of medieval military architecture. Some sections were built using rammed earth, a cost-effective yet durable technique common in Portugal at the time. Other parts, particularly the imposing towers, were constructed using locally sourced limestone and mortar, showcasing a combination of practicality and skilled craftsmanship.
The Muralha Fernandina played a pivotal role in safeguarding Lisbon during the 1384 siege by Castilian forces. Despite facing an army of 20,000 strong, the city, protected by Ferdinand’s wall, held firm. Today, only fragments of this once formidable structure remain, absorbed by the city’s growth or lost to time. Yet, even in their fragmented state, these remnants of the Muralha Fernandina whisper tales of a turbulent past, reminding us of the city’s resilience and the enduring power of human ingenuity.
