Beneath the bustling streets of modern Istanbul and the historic grandeur of the Ottoman capital lies a forgotten hydraulic system that kept the city alive for centuries. This episode explores the engineering marvels of Constantinople, focusing on the Yerebatan Sarnıcı (Basilica Cistern) and the legendary Water Supply Chain of Byzantium. We trace the journey of water from the Belgrade Forest through aqueducts like the Valens Aqueduct to the cisterns beneath Topkapi Palace. Lucas and Luna examine how Emperor Justinian I’s massive infrastructure projects laid the foundation for urban survival during sieges, and how later sultans, including Mehmed II and Süleyman the Magnificent, maintained and expanded these systems. Through the stories of engineers like Mimar Sinan and the daily lives of citizens dependent on public fountains (sebil), we uncover how control over water meant control over the empire itself, revealing a hidden layer of history where stone, shadow, and survival intersected in the heart of the Bosphorus. #YerebatanSarnici #BasilicaCistern #Constantinople #OttomanEngineering #JustinianIAqueducts #BelgradeForest #ValensAqueduct #MimarSinan #TopkapiPalace #WaterSupplyChain #ByzantineInfrastructure #SebilFountains #IstanbulHistory #OttomanHydraulics #MehmedII #SuleimanTheMagnificent #UrbanSurvival #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
