The Fort Bokar, often called Zvjezdan, is considered to be amongst the most beautiful instances of harmonious and functional fortification architecture. Built as a two-story casemate fortress by Michelozzo from 1461 to 1463, while the city walls were being reconstructed, it stands in front of the medieval wall face protruding into space almost with its whole cylindrical volume. It was conceived as the key point in the defense of the Pila Gate, the western fortified entrance of the city; and after the Minčeta Tower, it is the second key point in the defense of the western land approach to the city.
Bokar is said to be the oldest casemented fortress in Europe, which contains a small lapidary collection and numerous cannons.

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.
