Castle of Laguna de Negrillos is one of the fortress that belonged to the Conde Luna, with a characteristic structural style which features for a square floor and use of masonry , except in the corners, whose arris are built in ashlar stone. The keep tower and the crenellated walls are preserved.
It was arisen in the 13th century, although what you can seen today is the reconstruction carried out in the 15th century by Don Diego Fernández de Quiñones and Doña María de Toledo.
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.
