Corbera Castle is an impressive Muslim fortress, whose foundations lay on Roman remains. It has an irregular base, following the shape of the hill on which it rests. It was constructed in the 11th century to control the foothills of Murta and the coast. It is still possible to see the wall, the buttresses of the parade enclosure and the albarrana tower, which dates back to the Almohad period and it is one of the best-preserved towers in Europe. The complex was almost totally destroyed in 1521, during the Revolt of the Brotherhoods.

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.
