The mighty, unconquerable and romantic Predjama Castle or Predjamski Castle has become, due to its location and secrecy, an inspiration to many filmmakers, as they filmed here a number of films, television series and documentary films. The author of the bestseller Game of Thrones found here an inspiration for his projects. At this location, documentary series creators from Discovery Channel also recorded a part about the presence of ghosts inside the castle walls. However, the Predjamski Castle is also very unique, because it is listed in the Guinness World Records as the largest cave castle in the world and the only cave castle in the world that is fully preserved.

Each year it attracts around one hundred thousand visitors from all over the world. Maybe that is due to the fact that Postojna Cave and Predjama Castle are very close, since the castle is only 9 kilometers away from the Postojna Cave and 11 kilometers away from the Postojna city. So, if you have already visited the famous Postojna Cave, it is time to go on a medieval adventure and visit the picturesque Predjama Castle.

Interesting facts about Predjama Castle

Predjamski in Slovenian language means “in front of the cave”, which is quite reasonable, because beneath the castle there is an entrance to the Cave under the Predjama Castle, where the first part of the cave is opened for guided tours. Also, directly under and behind the cave castle there are many secret tunnels, which were used in the past to supply food and other necessities, when the castle was besieged by the Emperor’s army.

Predjama Castle is perched in the middle of a 123-meter high cliff. This is also its specialty, which makes its powerful appearance. Building a castle in a rock itself also has its purpose, because they were using its unique position in order to successfully protect themselves from numerous Turkish invasions and the rest of the army that was back then raging all over Europe.

Predjamski Castle was first mentioned in the 13th century, more precisely in 1274. At that time, it was named after the German word Luegg, by the German family, who bought the castle. They were also known as Adelsberg knights, which is in fact a German name for Postojna. Therefore, in the past the name of the castle was Postojna Castle.

Inside the Predjama Castle

Today, the Predjama Castle is a museum where you can see a collection of old weapons, paintings, a sculpture of the Virgin Mary from 1420. The cave castle is decorated with a very picturesque illustration about the medieval everyday life, and the impression is further enhanced by people figures in their natural sizes, performing various tasks.

There is also a hanged prisoner in the dark room and, of course, the legend about Erazem of Predjama also lives inside the castle. The old linden, under which the Erazem of Predjama was buried, is standing behind the cave castle, at least so says the legend. A girl, who was deeply saddened by the death of this famous knight, planted the linden on his grave.

Predjama Castle tour

Predjama Castle tour begins in the entrance tower, where you will learn about the history and the former owners of this cave castle. Among the equipment in other parts of the castle you can find a selection of original objects. There are many replicas of weapons, from lances and helebards, swords, battle hammers, arcs, crossbows and knight’s armor. The most luxuriantly equipped knight’s room is in the dining room, where you will be introduced to the castle life in the late Gothic era. In the renaissance hall on the third floor, the hunting trophies of the last owner, Prince of Windisch-Grätz, are exhibited.

Erazem’s Knight Tournament

Each year in July, traditional knight games, called the Erazem’s Knight Tournament, take place in front of the Predjama Castle. This is a very popular event, where knights on horses and swordsmen present their warfare skills. The horsemen, dressed in knight’s armor and equipment, illustrate the warfare and imitate soldiers in their battles in the middle ages, when the cave castle was besieged by opponents. Furthermore, near the old linden, masters of the old crafts exhibit their handmade masterpieces. There is also a gastronomic offer, which includes traditional medieval delicacies.

The legend about Erazem of Predjama

Knight Erazem was the most famous representative of the Luegg family. Only later he was known for his name, Erazem of Predjama, who resisted the imperial autocracy in the 15th century. Today, there are many legends about him, which on one side glorify him as a passionate, beautiful and noble knight, and on the other hand, they portray him as a robber, a rogue knight, who was ultimately killed on a toilet, inside the Predjama Castle.

The cave castle is accessible only from one side, but the legend says that knight Erazem supplied food and drink through a secret passage leading to the surface, inside the Predjama Castle. Meanwhile, the Emperor’s army besieged his castle for a year, but failed to break through. The army was not fatal for Erazem, however the tricks of his opponents were and lastly, a scam of his corrupt servant. After his death, the owners of the Postojna Castle were changing throughout the years, until the end of the Second World War, when it was nationalized.
