Its dramatic setting and noble past will excite your imagination… as it has excited writer George R. R. Martin, who got inspiration for death of one of his main characters in world' s bestselling- Game of thrones (Tywin Lannister). Listen to the legend of the rebellious knight Erazem of Predjama Castle and discover secret and underground caves which are part of its structure. Today’s castle dates from the Renaissance period, but the date of its construction is confirmed by a coat of arms of its owners, the Kobenzl family, from 1583. Concealed behind it is an older nucleus – the original cave castle. A symbol of defiance, the refuge of the bold, willful and rebellious knight Erazem of Predjama. Old depictions and descriptions – particularly from the last 200 years – prove that Predjama Castle was even then visited and admired by large numbers of travelers. It is still worth a visit today. There is always something happening at Predjama Castle, especially in summer, when the programme includes Erazem’s medieval tournament. Every year this brings together a large number of visitors and performers, who together stage a historical spectacle.
