This tour takes you into the turbulent past of Rijeka, and not just anywhere but exactly to the locations where that past took place. The tour of historical sites is also a trip to nature, where you can enjoy stunning views of the city. The focal point of the tour is a series of under- and above-ground fortresses that were built in the 30s of the 20th century as the defense of the then borders. With their construction and location, the fortresses are a masterpiece of military engineering of their era. At the same time, the route leading to them is equally interesting and historically important. The tour ends in the entrance hall of the unfinished underground fortress San Giovanni with socializing, a glass of wine and screening of a short film about the restoration of Rijeka after the Second World War.
