During the Great Siege of 1565, as Ottoman cannons pounded Fort St Elmo and the Grand Harbour turned red, the Knights Hospitaller faced a threat more insidious than gunpowder. With their surface cisterns poisoned or destroyed by Turkish miners, survival depended on a desperate, claustrophobic race against time. This episode explores the Aqqa l-Imramma, a hidden network of tunnels dug beneath Valletta’s limestone bedrock to tap into a deep freshwater aquifer. We follow the exhausted laborers who worked in darkness, armed with picks and prayers, while the battle raged just meters above their heads. The story reveals how this subterranean engineering feat, orchestrated under the direction of Grand Master Jean de Valette, ultimately broke the siege. It is a tale of grit, geology, and the quiet heroes who kept the island from turning to dust. #GreatSiegeOfMalta #KnightsHospitaller #JeanDeValette #AqqaLImramma #VallettaHistory #MediterraneanHistory #FortStElmo #OttomanEmpire #MilitaryEngineering #UndergroundTunnels #WaterSupply #1565History #MalteseCulture #LimestoneGeology #SiegeWarfare #HistoryPodcast #FexingoHistory #HistoricalResearch Keep every episode free: buymeacoffee.com/fexingo
