Keadeen Mountain
Keadeen Mountain (Irish: Céidín, meaning flat-topped hill)
Keadeen Mountain rises to 653 metres (2,142 feet) with a prominence of 334 metres. It sits at the southwestern edge of the Wicklow Mountains in County Wicklow, on its own small massif near Carrig Mountain and overlooking the Glen of Imaal.
It is the 152nd-highest peak in Ireland on the Arderin list and 184th on the Vandeleur-Lynam list.
The summit is marked by a robbed-out cairn. Just below it, a 300-metre-long and 40-metre-wide cursus runs down the western slope. The banks and ditches are still visible. The cursus faces the sunrise on the summer solstice and is thought to date from the Middle Neolithic period (about 3500–3000 BC). The surrounding area is rich in prehistoric features, with hillforts and many cairns on nearby slopes such as Cloghnagaune, Spinans Hill, and Baltinglass Hill.
Dwyer–McAllister Cottage lies at the northern base of Keadeen, at Derrynamuck, where Michael Dwyer, a leader in the 1798 rebellion, escaped a siege in December 1799 up the mountain.
The Irish name Céidín has also been used for a nearby townland in Kilranelagh parish; sometimes the peak was called Céidín Uí Mháil.
