The typical Galician noble fortress in Castro Caldelas with medieval origins has been splendidly conserved and restored and today functions as a library, cultural centre and exhibition venue.
The castle originally belonged to the House of the Counts of Lemos, and became part of the House of Alba in the 18th century. It was built in the 14th century as a fortress with a purely military function, and was renovated in the 16th century and converted into a palatial residence.Its floor plan is in the shape of an irregular polygon, as it adapts to the hill on which it stands. It comprises several parts or buildings, of which the rectangular keep and the clock tower are the oldest. Other surviving elements include the bailey, sections of the defensive wall, three square towers, the administrator's house, the palace (containing the library, a museum about the castle and other rooms), the interior sentry walk and the outer moat.
The location of the castle, on top of a mountain, also provides some panoramic views of the valleys below and it is easy to appreciate how impenetrable this town must have seemed to past aggressors.
You enter the castle (free of charge) through the main gateway and once inside you have unlimited access to all areas including the battlements.
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.
