The St. John Fortress is a complex monumental building on the southeastern side of the old city port, controlling and protecting its entrance. The first fort was built in the mid-14th century, but it was modified on several occasions in the course of the 15th and 16th centuries, which can be seen in the triptych made by the painter Nikola Božidarević in the Dominican monastery. The painting shows Saint Blaise, the patron saint of Dubrovnik.
Dominant in the port ambiance, the St. John Fortress prevented access of pirates and other enemy ships. Always cautious at the first sign of danger, the inhabitants of Dubrovnik used to close the entry into the port with heavy chains stretched between the St. John Fortress and the Kase jetty, and they also used to wall up all the port entries to the Great Arsenal.
Today, the fortress houses an aquarium on the ground floor, stocked with fish from various parts of the Adriatic Sea. On the upper floors there is an ethnographic and a maritime museum devoted to the Republic Maritime Period, the Age of Steam, the Second World War, and the section of techniques of sailing and navigation.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
