Magheraghanrush Court Tomb was built c. 3000 BC. It may have first been a simple construction with U-shaped court; the east part was added later.
Local legend has it as a Giant's Grave or Druid's Altar, or the burial site of Eógan Bél (d. AD 542), King of Connacht, although the Middle Irish poem Caithréim Cellaig says he was buried on Knocknarea and reburied on an island in Lough Gill.
The tomb is very large, 30 m long. The court is oval and located in the centre with two chambers at one end and a single chamber at the other, giving it the appearance of a man from above. The central court is not a perfect oval but is crooked in the middle, indicating that there was originally one court cairn which was then added to.
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.
