Under UNESCO protection, this fortress is one of the essential Venetian fortifications outside Venice, built for defence against the Ottomans. Famous as one of the most beautiful forts on the Adriatic. It was built on the islet of Ljuljevac, to which people eventually paved the way, and access to the fortress is now possible by land. At the time of its construction, in 1540, it cost as much as half of Dalmatia, 40,000 ducats. The builders of the fortress are the distinguished Venetian Sanmicheli family.

Šibenik, as one of the historical Croatian cities, was first mentioned in the middle of the 11th century in a document of King Petar Krešimir IV. The view is dominated by its four fortifications: St Nicholas, St Michael, St John and Barone. Of the sacred monuments, of which the city has 24 churches and six monasteries, from a distance, the Cathedral of St James, a unique monument of European sacral culture attracts the eye's attention. The cathedral was constructed entirely of stone, without any other materials and is the work of Juraj Dalmatinac and Nikola Firentinac, placed under the care of UNESCO World Heritage.

Gavan's Court is the name of a place on Lake Prokljan, where, in addition to the historical remains of the walls, according to locals, fragments of marble, decorated stones, Roman bricks, lead pipes and jewellery were found. According to the legend, a haughty rich woman, a "gavanuša", rudely chased off an angel disguised as a beggar for three times, and when the angel flooded her court, the Lake Prokljan was created. * (gavan = rich, arrogant, haughty man)
