St. John's Fortress: Guardian of Dubrovnik's Harbor
Explore St. John's Fortress in Dubrovnik: a historic maritime stronghold with panoramic views, housing a maritime museum and aquarium.
Dominating the port ambiance, St. John's Fortress is a testament to Dubrovnik's rich maritime history and strategic defense. The fortress's construction began in 1346 with the Dock Fort, and it underwent several upgrades through the 16th century. These modifications integrated various bastions and forts, including the old Fort Gundulić, into a single, formidable structure. The fortress played a crucial role in preventing access to pirates and enemy ships, with heavy chains stretched between it and the Kase jetty to secure the harbor entrance. Today, visitors can explore the fortress's interior, which houses the Maritime Museum and the Aquarium. The Maritime Museum showcases the city's maritime trade and tradition through objects, paintings, and documents. The aquarium features diverse fish species from the Adriatic Sea. Walking along the fortress walls offers panoramic views of the Old Town and the Adriatic, providing a glimpse into Dubrovnik's past and its enduring resilience.
