Explore the history of Rabtejn, a former Flossenburg branch, on a guided tour with underground tunnels, artifacts, and haunting stories—an authentic experience.
If you’re interested in understanding the darker chapters of European history in an authentic, well-organized setting, the Rabtejn guided tour offers a compelling look into a lesser-known part of the Holocaust and WWII history. Located in Ústí nad Labem in the Czech Republic, this two-hour experience takes you through the remains of a former underground factory that was converted into a concentration camp, and then into a haunting underground labyrinth. It’s a visit that balances education and reflection, enhanced by the insights of a knowledgeable guide.
What we particularly appreciate about this tour is its focus on local history and the tangible remnants of the camp, along with detailed exhibitions about the prisoners and air accidents in the area. One noteworthy aspect is the exclusive access to underground sections, which adds a layer of authenticity and a slightly eerie feeling that sticks with you long after the tour ends. A possible consideration is that the underground passages require some physical effort and the use of your own flashlight, so it’s not suitable for everyone. This tour is ideal for those with a serious interest in WWII history, Holocaust remembrance, or underground industrial sites, but may be less appealing for families with very young children or those with mobility issues.


The name “Rabtejn” originates from a sandstone massif that resembled a raven (Rabe), which was destroyed by mining, but the name persisted in the valley. Historically, this area was a hub of local textile production from the 1860s through early 20th century, with mills employing around a thousand workers. However, the story took a dark turn during WWII when, in October 1942, the site was annexed for military production, including parts for Junkers bombers and Messerschmidt fighters. To protect these industrial efforts, the underground factories were built—complex, secure, and now, heavily scarred by history.
In August 1944, the camp was established as a branch of the Flossenburg concentration camp. Over the course of eight months, prisoners cut 17,500 square meters of tunnels and 4.5 km of corridors—an immense feat of forced labor. After liberation, the site was repurposed as an internment and resettlement camp, adding layers to its historical significance.

The tour begins at a marked car park and a small house with signage, making it easy to find. You’ll be greeted by your guide, who will give a brief introduction to the history of Rabtejn and set the tone for the visit.
You’ll start with an overview of Rabtejn’s history, including its industrial past and the tragic stories of the prisoners. This helps contextualize the physical remains you’ll see later.
Next, you’ll enter the first underground section, known as Werk C. Here, the atmosphere shifts as you walk through corridors carved into the mountain. This section houses an exhibition featuring artifacts, documents, and photographs related to the camp’s history, as well as details about the air accidents in the area—something that many visitors find surprisingly sobering and poignant.
Guests have noted that “the underground is colder than expected” and that “it’s easy to get lost if you’re not paying attention,” so personal flashlights are recommended, especially for the second complex.
The tour continues to Werk B, another underground factory complex. Visitors need to bring their own flashlights here, highlighting the importance of being prepared. This part of the tour offers a more raw and exposed feel, with narrow tunnels and limited lighting, emphasizing the clandestine, secretive nature of the wartime production.
Throughout the experience, guides like Fabián Tours’ team are praised for their detailed knowledge and respectful approach. They often share stories beyond the basic facts, helping visitors appreciate the human stories behind the scars of history.

It offers great value for those interested in history, as it combines site access, expert narration, and exclusive underground sections.
