Exploring the Hidden Gem of Idrija Hills’ Underground Fortress Wine Tasting
Recently, I came across a fascinating experience in Slovenia that combines history, nature, and exceptional wine. The Wine Tasting in the Underground Fortress on the Idrija hills offers an unusual setting—an underground WWII fortification turned wine cellar—paired with the chance to sample ** Slovenian and international wines** alongside local farm-fresh foods.
What immediately caught my eye was the setting: three underground forts built by the Italian army between WWI and WWII, part of the famously formidable Alpine Wall. The fact that one of these forts now serves as a cozy wine tasting room makes for an experience that’s not just about wine but about stepping into history. Two things I really love about this tour are the guided expertise of Dejan, a third-level sommelier, and the authentic local food pairing—cheeses, salami, and homemade bread—straight from nearby farms.
A possible consideration is the price point—at around $115.76 per person, it’s an investment, but one that includes quality guidance, a memorable setting, and five thoughtfully chosen wines. If you’re a wine enthusiast or history lover, it’s well worth it. Just keep in mind that this is a private tour; the intimate group setting enhances the experience but also means it’s less of a generic tasting and more personalized.

The Hidden WWII Forts Turned Wine Cellar
What makes this experience stand out is how it transforms a piece of military architecture into a cozy, atmospheric wine tasting room. As you descend into the underground tunnels, you can’t help but think about the soldiers who once manned these defenses during turbulent times. Today, those tunnels are filled with the aroma of wine and local delicacies, a stark contrast that adds layers of depth to your visit.
The tour begins at the House on the Hill property, which encompasses three underground forts, each with its own purpose—one for relaxation, another for tasting, and the third shrouded in secrecy. The second fort, dedicated to wine tasting, is where the magic happens. The temperature stays consistently cool, ideal for storing wine and creating a perfect environment to appreciate nuances of flavor without distraction.
Dejan, the guide, is noted for his enthusiasm and vast knowledge about wines, making the experience engaging and educational. His expertise shines through as he walks you through the selection, pairing each wine with local cheeses and cured meats that come from nearby farms. Reviewers praise him for his “great experience and knowledge,” which makes the tasting both accessible and inspiring.

Guests have raved about the quality of wines and the delicious, locally sourced food. One reviewer called it an “astonishing wine tasting,” highlighting the “great taste” of the collection.
