Located at 89 meters in height, the Pedres castle was built between 1296 and 1322 during the Pisan-Aragonese domination period during the ascent of the Visconti family. It is characterized by two squares, one upper and one lower, surrounded by polygonal walls, reachable through stairs built with large granite boulders. Its position allowed to control the territory up to the Gulf of Olbia.
In 1339 the castle was entrusted to the hospital friars of Saint John of Jerusalem. From the second half of the fourteenth century it was occupied by the Aragonese and then by the Giudicato of Arborea. The castle met a definitive abandonment at the beginning of the fifteenth century, coinciding with the decline and depopulation of Civita.

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.
