Labyrinth

This guide to the Labyrinth beneath Budapest's Castle Hill walks these thermal-water tunnels by lantern light, tracing centuries of use as a wine cellar, a prison and later a Cold War bunker. It focuses on the most notorious prisoner held here in the 1460s: Vlad the Impaler, the Wallachian prince whose reputation inspired Dracula, thrown into these passages after his ally the Hungarian king turned against him. Take the after-hours lantern tour, when every other light is switched off.
