Discovering Hidden WWII Secrets Beneath Lazio: A Deep Dive into the Underground Fortress San Giovanni
This tour in Lazio offers a unique blend of history, adventure, and relaxation. For just $35 per person, you get an opportunity to explore a part of Rijeka’s past that is usually off-limits to the public—an underground fortress linked to WWII and earlier military battles. It’s not your typical sightseeing experience; instead, it’s an immersive journey into the unknown, led by expert guides who bring history to life with special effects and storytelling.
What makes this experience stand out is the opportunity to venture into the unfinished underground fortress San Giovanni, a site that’s often hidden from travelers. The tour’s thoughtful combination of educational content and sensory effects creates a vibrant, memorable atmosphere—almost like stepping back into the past. Plus, ending the tour with a glass of local wine adds a relaxing touch that balances the adventure.
One thing to keep in mind is the underground temperature, which hovers around 14°C, so bringing warmer clothes is recommended. Also, this tour isn’t suitable for everyone—particularly those who are claustrophobic, have epilepsy, are under 10, or are over 70. But for history buffs, curious travelers, or those wanting a different perspective on WWII, this tour promises an engaging, authentic experience.
This experience is particularly suited for travelers seeking a mix of history and adventure without a massive time commitment. If you love discovering secret sites away from the usual tourist crowds, or if you appreciate stories that uncover the lesser-known aspects of a city’s past, this tour is worth considering.
