Knocknarea is a large prominent hill west of Sligo town in Ireland, with a height of 327 metres. On the summit of Knocknarea is a large cairn about 55 metres wide and 10 metres high, making it the largest cairn in Ireland outside Brú na Bóinne in Meath. Although it has not been excavated by archaeologists, it has many features of a classic passage tomb.
The cairn is flat-topped and several kerbstones can be seen on the northern side. It is believed to date to around 3000 BCE, during the Neolithic (New Stone Age). It is known in Irish as Miosgán Meadhbha (Meadhbh's heap), and in English as Maeve's Cairn or Maeve's Tomb. Meadhbh is a queen of Connacht in Irish mythology, who is believed to have originally been a goddess.
The ancient cairn is a protected National Monument. In recent years, archaeologists have warned that it is being eroded by hikers climbing on it and moving or removing stones. The large number of climbers is leaving scars on the cairn and may be destabilizing the tomb inside. Irish folklore holds that it is bad luck to damage or disrespect such tombs and that doing so could bring a curse.

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.
