My journey into the heart of the Czech Republic took an unexpected and profoundly unsettling turn when I found myself facing an overnight stay in a Cold War-era nuclear bunker. This wasn’t merely a tour; it was an immersive, and for me, terrifying experience that pushed the boundaries of my personal comfort zone. As someone who grapples with severe claustrophobia, the very notion of being confined underground for an entire night was a daunting prospect. When my itinerary initially hinted at a bunker visit, my imagination optimistically conjured images of a brief exploration, followed by the familiar comforts of a hotel. Reality, however, had a far more intense and memorable plan in store for me.

Descending into History: The 10-Z Nuclear Bunker in Brno
Our unique accommodation for the night was the infamous 10-Z Bunker, strategically located right in the vibrant heart of Brno, Czech Republic. This historical marvel dates back to the height of the Communist era, constructed in 1959. Its primary, grim purpose was to serve as a civil defense shelter, offering protection to key city officials and political representatives in the event of an anticipated American or Soviet bombardment of Brno. Envisioned as a last bastion of survival, the 10-Z Bunker was engineered to house up to 600 individuals for a critical period of three days, providing a stark glimpse into the anxieties of the Cold War.
Today, the 10-Z Bunker has been transformed from a secret government stronghold into a unique museum and a truly unconventional hotel, allowing the general public to step back in time and experience the chilling reality of a nuclear war bunker. It stands as a powerful testament to a turbulent past, inviting visitors not just to observe, but to actively participate in a piece of living history. Exploring its deep corridors and chambers offers an unparalleled perspective on the preparations and fears that gripped nations during an era defined by geopolitical tension and the looming threat of global conflict.




The Chilling Reality: Inside the Bunker’s Uninviting Interior
Stepping inside the 10-Z Bunker was an immediate sensory assault. The interior, as one might grimly expect from a Communist-era nuclear shelter, was anything but welcoming. Far from a cozy retreat, it was a space designed for utility, not comfort – stark, utilitarian, and permeated by an oppressive sense of history. Every corner, every corridor, echoed the gravity of its original purpose, devoid of any warmth or inviting features that typically characterize overnight accommodation.
The most pervasive and memorable aspect of the bunker’s environment was the cold. While I had read that the average temperature hovers around 57 degrees Fahrenheit (14 degrees Celsius), no numerical figure could adequately prepare me for the visceral reality. This wasn’t merely a cool temperature; it was a deep, damp cold that seemed to seep into your very bones, leaving a pervasive chill that blankets you, no matter how many layers you wear. The air itself felt heavy and thick, lacking the freshness of the outside world, contributing to the unsettling atmosphere.
Our sleeping quarters were equally spartan. My designated room featured three metal beds, each topped with a thin mattress that offered minimal cushioning against the hard frame. A scratchy sleeping bag provided the main source of warmth, complemented by a threadbare towel and a small, unyielding pillow. These were the basic provisions for a night spent reliving a hypothetical catastrophe, a stark reminder of the bunker’s true, grim function.
Adding to the surreal quality of the experience were the truly bizarre decorations and items scattered throughout our room. Amidst the austere setting, we found skis and sleds, seemingly out of place and purpose, along with a peculiar statue of a man canoeing perched on the nightstand. These incongruous objects only amplified the unsettling feeling of being in such an extraordinary place, blurring the lines between historical exhibit and an almost theatrical, eerie display. The strangeness of these items, combined with my mounting anxiety, made it difficult to fully comprehend or process my surroundings, contributing to a sense of unease that lingered throughout the night.


A Battle Against Claustrophobia and Fear: My Hours Underground
This overnight stay was undoubtedly an experience etched permanently into my memory, not least because it forced me to confront my deepest fears. A profound sense of accomplishment swelled within me for not succumbing to my claustrophobia and impulsively booking a conventional hotel. Yet, even as I felt immense pride, a part of me still couldn’t quite believe I had endured the night. Fortunately, fate had provided a subtle escape route: after a late dinner, we returned to the bunker, meaning I only had to truly “survive” a mere four hours before my scheduled taxi pickup at 4:45 am. This pre-arranged departure served as a crucial psychological lifeline, transforming the daunting task into a manageable 240-minute countdown.
The initial hour inside the bunker felt interminable, each minute stretching into an eternity. I sat rigidly on the metal bed, cocooned in the sleeping bag, desperately attempting to meditate and calm my racing thoughts. Every distant creak, every muffled sound, every subtle vibration within the labyrinthine structure sent a jolt of alarm through me. My imagination, fueled by fear, conjured vivid, unsettling scenarios, making me feel as if I were trapped in the opening scene of a horror movie, merely awaiting the inevitable terrifying climax.
I was incredibly fortunate to share this unnerving experience with Eulanda from Hey Dip Your Toes In. Her presence was invaluable. We engaged in continuous conversation, a shared effort to process the surreal reality of our situation and to calm each other’s frayed nerves. I won’t sugarcoat it; our dialogue included a fair amount of emphatic language and many deliberately deep breaths as we collectively grappled with the sheer absurdity, and terror, of sleeping in a nuclear bunker. Her companionship was a beacon in the oppressive darkness, transforming a potentially solitary ordeal into a shared journey of endurance.

Triumph Over Terror: Emerging from the Depths
Despite the relentless anxiety, I did manage to drift into an hour or two of restless, light sleep. However, the moment my alarm pierced the bunker’s silence, a wave of profound relief washed over me. I practically catapulted out of bed, eager to escape the subterranean confines and make my way to the promised fresh air and my waiting taxi. The journey out of the bunker and into the crisp morning light felt like an exodus, a profound release from a psychological burden.
While an overnight stay in a nuclear bunker isn’t an experience I’m keen to repeat in the future, I emerged from it with an undeniable sense of triumph. It was a challenging, fear-inducing adventure, but more importantly, it was a battle against my own deeply ingrained fears that I ultimately won. This unique encounter in Brno taught me valuable lessons about resilience and the power of facing one’s phobias head-on. It reinforced the notion that sometimes the most uncomfortable experiences yield the most personal growth and memorable stories. I am immensely proud of myself for not letting fear dictate my journey and for embracing such an extraordinary, albeit terrifying, part of my travel itinerary.
