Dubrovnik Aquarium, Marine research facility in Old Town Dubrovnik, Croatia.
The Dubrovnik Aquarium displays fish, mollusks, and other Adriatic Sea creatures inside the stone vaults of Fort St. John in the Old Town. The exhibition shows the variety of life in the local waters and how these animals inhabit their marine environment.
Fort St. John was built in the 16th century to defend Dubrovnik's old harbor and remained a key part of the city's defenses for centuries. Today its ground level houses the aquarium while maintaining the fort's original stone structure.
The facility is managed by the University of Dubrovnik's marine research institute, showing how the institution connects scientific work to the local community. Visitors can see how local research contributes to understanding and protecting the creatures that share the Adriatic with the city.
Visit in the morning when it is less crowded, making it easier to observe the animals comfortably. The facility is fully wheelchair accessible, and the underground rooms stay cool and pleasant throughout the year.
The facility rehabilitates injured sea turtles from the Adriatic Sea before releasing them back into the water, allowing visitors to witness this rescue work firsthand. This hands-on conservation effort makes the facility more than just a display space.

The old town of Dubrovnik sits on the Adriatic coast and shows buildings from the 13th to the 17th centuries. The city was an independent maritime republic for hundreds of years and developed its own architecture that combines Venetian and local elements. The city walls enclose a compact core of palaces, churches and public squares built on limestone. The main street Stradun runs straight through the town and connects the main gates. At both ends stand fountains from the 15th century that once secured the water supply. The Rector's Palace shows how the elected rulers lived and worked, while Sponza Palace once served as a customs house and mint. The city wall itself is walkable and offers views of the sea and the rooftops of the old town. Several fortresses reinforced the defenses: Fort Lovrijenac perches on a rock outside the walls, Revelin Fortress protected the eastern approach, and the sea wall ends at St. John's Fortress, which now houses a maritime museum. Lokrum Island lies just a short boat ride away and was once a monastic site. Today plants from different climates grow there. The beaches around Dubrovnik often sit in small coves between rocks, where the water is clear and deep. The Dominican Monastery and Franciscan Monastery preserve art and manuscripts from the republic's era. The cathedral was rebuilt in baroque style after an earthquake in the 17th century destroyed the older church.
