Lough Gill (Irish: Loch Gile-meaning bright, white or radiant lake) is a freshwater lough (lake) mainly situated in County Sligo, but partly in County Leitrim, in Ireland. The lake is mentioned in the poetry of W. B. Yeats.
Lough Gill and the district of Calry adjoining it is famous for its beautiful scenery.
In 1836 Thomas O'Connor of the Ordnance Survey noted a saying amongst the people that went "Connacht is the Grianán of Ireland, Cairbre is the Grianán of Connacht, Calry is the Grianán of Cairbre and the Hill is the Grianán of Calgaich. Gríanán is a word meaning literally "sunny place" and implies a place of great natural beauty. The hill of Grianán is at the eastern shore of Lough Gill.
Location and environment
Lough Gill is about 8 km or 5 miles long and 2 km or 1 mile wide. The Lough Gill system consists of the river Bonet that flows into the eastern end of the lake and the River Garavogue which drains the lake to the west near Sligo Town.
The picturesque lake is surrounded by woodlands, such as Slish Wood, Dooney Rock, and Hazelwood all of which contain popular nature trails and viewing points along the lake. The wooded hills of Slieve Killery and Slieve Daean dominate the south shore.
Flora and fauna
Lough Gill has a unique micro climate and is noted for the high number of rare or scarce animal and plant species. It is a candidate SAC (Area of Special Conservation) for three habitats listed on Annex I of the E.U. Habitats Directive, including one with priority status including, old oak woodlands, alluvial forest, and the naturally eutrophic lake, all habitats listed in the EU Habitats Directive.
The Lough Gill water system gets a very early run of spring salmon.
The vegetation of the area was dominated by mixed woodland from 4,600 BC to at least 1400 AD. Scots pine was dominant until 3,400 BC. In a scientific study, Arbutus unedo pollen was found at Slish Lake dating from as early as 100 AD, and so it is considered native to this area.
The woods surrounding the lake are dominated by oak (Quercus spp.), rowan (Sorbus aucuparia) and willows (Salix spp.).The shores of the lake are home to the northernmost specimens of the rare Mediterranean strawberry tree (Arbutus unedo) in the world. It is a small evergreen tree of the family Ericaceae, which in Ireland can grow to be a forest tree, reaching heights of up to 15 metres. Its Irish name is caithne.
The lake shore supports several rare plant species, including yellow bird's-nest (Monotropa hypopitys), lady’s mantle (Alchemilla glaucescens), ivy broomrape (Orobanche hederae), black bryony (Tamus communis), intermediate wintergreen (Pyrola media) and bird's-nest orchid (Neottia nidus-avis).
It is also home to the following rare or protected species, sea lamprey, river lamprey, brook lamprey, white-clawed crayfish, Atlantic salmon and otter.
In the early historic era (5th-8th centuries), the area was home to a branch of the Cálraighe. Parke's castle, a plantation fortified house on the northern shore, was built in the early 17th century by Captain Robert Parke on the site of a former tower house of the Uí Ruairc clann. The Uí Ruairc clan ruled the area from about the 7th century up to the time of Oliver Cromwell.
The two largest islands on Lough Gill, namely, Church Island or Inis Mór, and Cottage Island, each contain ecclesiastical remains. An early Christian ruin lies on Church Island and belonged to the O' Rourkes, kings of Bréifne. The church is said to have been founded by St Loman.
In 1416, according to the Annals, "the church of Inis Mor was burned, and Screaptra O Curnin and the Leabhar Gearr of the O' Curneens, as well as many other precious objects, were burned."
The building is oblong, has loophole windows and a recess at one end. Near the door there is a cavity in a rock, known as 'Lady's Bed', which was a frequent place of pilgrimage for pregnant women. St Loman, whose feast day is on 4 February, is mentioned in the Martyrology of Tallaght. The ruin on Cottage or Gallagher's Island belonged to the church of Kilross, in Riverstown parish, which in turn belonged to the Premonstratensians of Trinity Island on Loch Ce.
In 1196 - Congalach, the son of Farrell O'Rourke, was slain by the men of Lúighne, on Slieve-da-én (Mountain of the Two Birds).
1346 - A war broke out between O'Rourke, i.e. Ualgarg, and Rory, the son of Cathal O'Conor; and an engagement took place between them in Calry-Lough-Gill, in which O'Rourke was routed, and all his gallowglasses slain, i.e. Mac Buirrce, and Mac Neill Cam with their people. O'Rourke was afterwards pursued by Rory O'Conor and the Clann-Donough, and was killed by Mulrony Mac Donough. This was a lamentable deed.
The lake became part of the Hazelwood estate in the 17th century.
The Metrical Dinnsenchus tells the following story of how the lake came to be and how it got its name.
"Bright Gile, Romra's daughter, to whom every harbour was known, the broad lake bears her name to denote its outbreak of yore. The maiden went, on an errand of pride that has hushed the noble hosts, to bathe in the spray by the clear sand-strewn spring. While the modest maiden was washing in the unruffled water of the pool, she sees on the plain tall Omra as it were an oak, lusty and rude. Seeing her lover draw near, the noble maid was stricken with shame: she plunged her head under the spring yonder: the nimble maid was drowned. Her nurse came and bent over her body and sat her down yonder in the spring: as she keened for Gile vehemently, she fell in a frenzy for the girl. As flowed the tears in sore grief for the maiden, the mighty spring rose over her, till it was a vast and stormy lake. Loch Gile is named from that encounter after Gile, daughter of Romra: there Omra got his death from stout and lusty Romra. Romra died outright of his sorrow on the fair hill-side: from him is lordly Carn Romra called, and Carn Omra from Omra, the shame-faced [gap: extent: two lines] Loch Gile here is named from Gile, Romra's daughter."
Carn Romra and Carn Omra are the names of the two large neolithic cairns on Cairns hill overlooking the lake.
Sliabh Dhá Éan is also associated with myth.
Amenities and events
The lake is home to the Lough Gill 10 km Swim for the North West Hospice in Sligo. This annual fundraiser began in 2011 raising over €34,000 to date for the hospice also winning the coveted Irish Long Distance Swimming Association swim of the year in both 2011 and 2012. It is run by a committee made up of local swimmers and friends of the family of Neill McGarry, for whom the event trophy is dedicated. 57 swimmers completed the 2012 swim.
The first man to successfully swim the English Channel, Captain Matthew Webb, used the lake as part of his training for the feat. He was a friend of W.B. Yeats's grandfather, who lived in the area.
