Neither the origins nor the date of construction of San Romualdo Castle is certain, although historians are fairly sure that this castle dates back to medieval times. Built in the Mudéjar style, it was first mentioned in 1268. It is thought to have been used as both convent and fortress.
The castle was officially declared as a historic monument by the Spanish authorities in 1931 and is easily located near the town centre, half way between the town hall and the Zuazo Bridge.
References: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.
