Kastellet

This guide to Kastellet in Copenhagen opens on a January night in 1772, when guards dragged Johann Friedrich Struensee, the German doctor who had come to rule Denmark, from his bed after an affair with the young queen. It follows the court coup that ended his power and the months he spent shackled inside the citadel's Fortunstokken building awaiting trial. Listen for how a green, peaceful fortress with a working windmill still holds that barred window today.
