The Mound of Down is an ancient monument which gives County Down its name. Originally the home of Celtair - Rath Celtair - this became a stronghold for the Dál Fiatach, a powerful army who once owned the Isle of Man. It is a good example of an Iron Age defensive earthwork in the middle of which a Norman Motte and Bailey was built by John de Courcy after his defeat of Rory Mac Donlevy in 1177.
Originally on the shores of Strangford Lough this site was an excellent military base. The land around has been reclaimed since the 1700s. Today the site is an impressive motte and bailey style fort which was abandoned before completion.
From the top of the incomplete mound you have an excellent view over Down Cathedral and Inch Abbey. In the distance are the Mourne Mountains. During the summer the site is left to grow as a wildlflower meadow.
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.
