Piedrabuena Castle is part of defense line of Guadina and Tajo rivers near Portugal border. The oldest parts date from the late 14th and early 15th centuries. It has been head of the Encomienda of the Order of Alcántara since the 13th century.
The exterior enclosure is a quadrangular construction with cylindrical towers at the corners. In the interior there are four corridors, the keep and the prison tower. The residential function of this building is easy to see, with galleries open to the outside and a cloistered patio, all in the manner of an urban palace.
Today Piedrabuena Castle is privately owned.
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.
