Château de Saint-Sauveur-le-Vicomte was built in the 11th and 12th centuries. It was besieged twice during the Hundred Years War. The city walls were breached by cannon in 1374. This is believed to have been among the first successful uses of guns against city walls in history. Today it is partially ruined, but still a notable castle with massive 14th century towers and a 12-15th century abbey.

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.
