Tito hosted world leaders at this Slovenian hotel, then behind the iron door, a great secret was revealed

In 2016, during renovation work at Hotel Jama near Postojna, workers discovered four hidden rooms behind iron doors in the basement. The rooms contained telephone equipment, magnetic tape recorders, switches and other communication and surveillance gear, according to reports from local media. These rooms had remained sealed for nearly 28 years, untouched by anyone, including hotel staff. When the doors were finally opened, the equipment was covered in dust, giving the impression that people had simply stopped working and left. The discovery took place during the renovation of the basement area, close to the laundry room and storage space. According to accounts accompanying the story, even hotel employees were unaware of the existence of these rooms. The hidden spaces were part of a former communications and surveillance center, which operated during the Yugoslav era. The rooms were reportedly used to monitor large parts of Slovenia’s Primorska region, or western Slovenia near the Adriatic Sea and the Italian border. The facility was connected to both civilian and military telephone exchanges, with cables running through a narrow, windowless corridor throughout the building. An antenna was once located on the roof. The hidden rooms could be accessed from multiple points, through the reception area, club spaces, and storage areas. One of the passages reportedly led directly into Postojna Cave itself. In the first-floor clubrooms, Josip Broz Tito, the long-time leader of Yugoslavia, often spent time with his guests. During the Yugoslav period, the hotel attracted high-profile visitors such as Soviet leader Leonid Brezhnev and the last Shah of Iran, Mohammad Reza Pahlavi. These guests would have been of interest to security services, though there is no definitive documentation confirming who exactly was monitored or surveilled within the hidden rooms. Postojna's strategic location in the former Yugoslavia played a key role in the establishment of the secret facility. The town had a significant military presence, with a base of the Yugoslav People's Army (JNA) situated on a hill overlooking the hotel. Given these circumstances, the location of a communications and control center inside Hotel Jama seemed far from coincidental. The hotel was designed by architect Tihomir Stepanović from Izo. According to stories shared with tourists today, he received a special assignment while serving under the military regime to design the hidden rooms within the building. He was allegedly instructed not to speak about their existence after completing the project, and his plans were later taken away. Stepanović reportedly never entered the rooms again after they were completed. When the hidden rooms were eventually opened, around 30 empty boxes were found, along with one encrypted audio recording. The recording referenced codes such as “Planina 1,” “Planina 2,” “Planina 3,” and “Reka.” This has led to speculation that the center might have been linked to a military communications hub in the village of Reka. The fate of the remaining materials remains unknown. It is believed that the equipment and documents were removed when the system was shut down, likely in the early 1990s during Slovenia’s path toward independence. Today, the hidden rooms have become a tourist attraction. While the lack of official records means the story remains a mix of historical facts, anecdotes, and legends, the hotel owner later obtained permission to renovate and open the spaces to the public. The hidden rooms of Hotel Jama continue to draw curiosity and fascination from visitors seeking a glimpse into the past.
