Aquarium Pula is hands down the most popular aquarium in Croatia, and it's not hard to see why. Nestled within the historic walls of Fort Verudela, this place offers a fascinating blend of history and marine life. The fort, which is over 130 years old, was once part of the formidable Austro-Hungarian defense complex known as Fortress Pula. Today, it beautifully marries Pula's rich military past with the vibrant life of the Adriatic Sea. Just a short 3 km hop from the heart of Pula, the fort has been transforming into an aquarium since 2002. Now, it houses around 200 different animal species. Visitors are often drawn to the mesmerizing sharks, ethereal jellyfish, and whimsical seahorses. But if you ask me, the Marine Turtle Rescue Center is an absolute must-see. It's the aquarium’s pride and joy when it comes to marine conservation efforts. If you're up for some breathtaking views, head to the fort’s rooftop. Since 2017, it features a stunning steel dome gracefully arching over the old artillery block. This dome marks the culmination of the aquarium's ambitious project to revitalize the fort, adding three massive tanks, each holding an impressive 50,000 liters, to showcase even more of the underwater wonders. And while you're there, don't forget to soak in the panoramic vista of Pula and the shimmering sea beyond. It's truly a view that will etch itself into your memory. If you're curious about the local culture, Pula itself offers a treasure trove of Roman architecture and lively street markets that are definitely worth exploring. So, whether you're a history buff, a marine enthusiast, or just someone looking for a unique adventure, Aquarium Pula is a destination that promises to captivate your imagination.
