Historical Origins 

So, the Predjama Castle was first documented in 1274 under the German name Luegg, and the Patriarch of Aquileia constructed it in Gothic style. Its strategic location, built under a natural rocky arch high in a stone wall, was chosen specifically.

Defensive Purposes

The purposes were said to be defensive. Hence, access to it was difficult, enhancing its fortification against invaders. The castle first served as a stronghold for the Patriarchs of Aquileia, who named it. In a rough Latin translation it means—"in front of the cave".

Early Expansions

The Luegg noble family, who were also called the Knights of Adelsberg, got their hands on the castle and did a lot of work to expand and strengthen it, turning it into a strong military base.

The Famous Robber Baron 

This place is associated with Erasmus of Lueg, a local figure akin to a Slovenian Robin Hood. Also known as Erazem Predjamski, he was a prominent figure in the 15th century, renowned as a robber baron and knight linked with this area.

Erasmus's Background

Apparently, he was the son of the imperial governor of Trieste and gained notoriety for his defiance against the Habsburgs after killing Marshal Pappenheim. This man, Marshal Pappenheim, had apparently dishonored his deceased friend, Andrej Baumkircher.

Rebellion And Alliance

Following this act, he sought refuge in Predjama Castle, where he aligned himself with King Matthias Corvinus of Hungary. From this stronghold, he let out attacks against Habsburg estates and towns, which led to a rise in tensions further.

Secret Passage System 

In response, Emperor Frederick III ordered a siege to capture or kill Erasmus. The siege lasted for about 366 days, during which Erasmus utilized a network of hidden passageways within the cave system beneath the castle to resupply himself and his men.

The Siege Of Predjama Castle

The siege (1456–1457) was led by the governor of Trieste, Andrej Ravbar, who commanded a large force that surrounded the castle day and night. Despite their efforts to starve Erasmus and his men out, they were baffled by his endless supplies of food.

Erasmus's Demise 

Ultimately, Erasmus's downfall came through betrayal by one of his servants. According to popular legend, while Erasmus was using the toilet located on a high floor of the castle, the servant signaled the besieging forces by lighting a candle in his window.

Fatal Betrayal 

It was this act that led the Habsburg archers to go after the man with cannon fire. One unlucky cannonball hit the castle's outhouse and killed Erasmus on the spot. This led to the well-known "story" of his death on the toilet.

Post-Erasmus Reconstruction 

Following the siege and destruction of the main castle, the ruins were acquired by the Oberburg family. In the early 16th century, the Purgstall family undertook a major reconstruction. However, this newly built structure was short-lived.

Met With Disaster

In 1511, a devastating earthquake struck the region, specifically on March 26, and caused great destruction to Predjama Castle. This extremely beautiful piece remained in disrepair for several decades until Baron Philipp von Cobenzl took ownership in 1567.

Renaissance Renovation

He initiated a comprehensive rebuilding project and finished it in 1570. This reconstruction was a transition from Gothic to Renaissance architecture, resulting in the castle's current façade, which is pressed against a vertical cliff.

Habsburg Connection 

In 1567, Archduke Charles of Austria rented out the castle to Baron Philipp von Cobenzl. After 20 years of making payments, the baron finally bought it in 1587, which kicked off his family's long history with the place.

Noble Summer Residence 

In the 18th century, Predjama Castle became one of the Cobenzl family's favorite summer residences. It was frequented by notable figures Count Ludwig von Cobenzl and Philipp von Cobenzl (an influential Austrian statesman and art collector).

19th Century Ownership 

Count Michael Coronini von Cronberg inherited the castle in 1810, continuing the legacy of noble ownership. Then, in 1846, the castle was finally sold to the Windischgrätz family, who maintained ownership until the end of WWII.

Communist Era Transformation 

Following WWII, the Yugoslav Communist authorities confiscated and nationalized Predjama Castle. It was quite a big change in the castle's status, as it turned from a private residence into a public museum aimed to preserve the rich history.

Nationalization Moves

The nationalization occurred after the deposition of King Peter II and the establishment of the Socialist Federal Republic of Yugoslavia. The museum holds a series of artifacts, like old weapons, paintings, sculptures, and displays that illustrate medieval life.

Original Entrance Design 

The original entrance to the castle was placed high up on the cliff face, which served as an added layer of security. To access this original entrance, retractable ladders were used. Today, two faint doors can still be seen at the original entrance site.
