Castillo de Doña Blanca is a tower built in the 15th or 16th century to watch the Cádiz bay. It is named after lady Blanca de Borbón, who was imprisoned there.
The tower is built to the archaeological area. The remains of walls, necrópolis and parts of houses date from the eighth to the third century BC and were built by the Phoenicians. It is considered an ancient city with a significant development and urban planning, which shows the great power of this port city. The first traces of occupation in the mountains and around date back to the Copper Age.
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.
