The Glass Scales: Karlsruhe and the Architecture of Democracy

How do you build a democracy that cannot be destroyed? After the catastrophic failures of the Weimar Republic and the horrors of the Nazi regime, Germany had to answer this exact question. Join us on a journey through Karlsruhe, the 'Residence of Law', where the nation's judicial heart beats. We will explore how architecture, geography, and history intertwine to protect fundamental rights. From transparent glass pavilions designed to strip away authoritarian mystique, to grand palaces repurposed for modern justice, this tour reveals the hidden tensions of defending freedom.
