Amidst the picturesque streets and ancient piers that the city of Portorož is famous for, lies a true window into the underwater world of the Adriatic — the Piran Aquarium. Located in the historic building of the former Maritime School right at the water's edge, this site is one of the most charming and educational attractions Slovenia offers to nature lovers.

This is not just an exhibition of marine life, but a carefully designed space in the inner courtyard of the Piran pier. Here, on Kidričevo nabrežje, visitors can see a unique combination of history and biological diversity. The exposition includes dozens of tanks of various sizes — from intimate containers to an impressive 2000-liter aquarium built directly into the wall.
One of the institution's features is its thoughtful lighting: some halls use natural daylight, creating a special, almost magical atmosphere. A team of professionals, including an on-staff diver, monitors the health of the inhabitants and the clarity of the water, ensuring excellent living conditions for the sea creatures and a great view for guests.
