Journey into the heart of a real-life fairytale at Predjama Castle, a dramatic Renaissance-era stronghold built directly into the mouth of a 123-meter cliff near Postojna in Slovenia. First documented in 1274 and rebuilt in its current form around 1570, this unique fortress served as the hideout of Erazem of Lueg — a legendary Robin Hood–style knight who used secret caves and tunnels to evade the Habsburgs. Inside the castle and its subterranean passages, interactive exhibits and engaging storytelling bring medieval intrigue, architectural ingenuity, and cliffside legends to life.
