Fortica in Kastav, Croatia, is a historic fortress that once served as a lookout point protecting the region from invaders. Today, it offers one of the most stunning panoramic views over the Kvarner Bay, stretching across Rijeka, Opatija, and all the way to the islands in the Adriatic. An interesting fact is that Fortica is not just a military relic—it’s also a beloved local spot for open-air events, especially during the Kastav Cultural Summer festival. And if you’re visiting with a keen eye, you might stumble upon a little treasure: our friend loborosh hid a penguin stone here, tucked inside a tree trunk at a viewpoint overlooking the city—a playful reminder that even history can have a penguin twist.
