The castle of Salemi is one of the best preserved castles in Sicily. Inside, the library and the resurgence museum are housed. The castle has Norman origins and dominates the town with its trapezoidal shape and square, 20 meters high, corner towers, and a cylindrical tower.
The castle was built by Norman King Roger around 1077 to the site of Roman-Arab fort. Frederick II altered it in the 13th century.
In 1441, on December 11, in the castle of Salemi a confederation made up of Salemi, Trapani, Mazara, Monte San Giuliano and by the barons of Castelvetrano and Partanna was formed which undertook the defense, and bore the costs, of the Queen White and Royal House of Aragon. Salemi was, therefore, more fortified and garrisoned during the raids of the Turks.
The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
