Situated on the left bank of the Navia Estuary, Castro de Coaña is a hilltop settlement (4th Century BC) surrounded by walls and accessed from the south. The main defensive structure is located precisely in the south and consists of a wide ditch dug into the slaty subsoil finished off by a wall. Inside, the settlement is divided into several sectors.
It has a diamond shape in which the three areas can be clearly distinguished. The acropolis is a triangular enclosure surrounded by a wall, not used for housing. Access to this area was protected by a square tower. The northern residential sector spreads out beneath the north wall of the acropolis, mostly consisting of circular huts. Some of them are accessed via a hall or corridor. The walls are made of slate with rounded corners.
Inside the residential sector near the gate to the acropolis, there are two groups of buildings associated with channelling water and a pool, a granite vessel called a 'bath', which suggests that it was used for bathing or rustic saunas.
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.
