County Wicklow in the context of "Dublin Area Rapid Transit"

Charles Stewart Parnell (27 June 1846 – 6 October 1891) was an Irish nationalist politician who served as a Member of Parliament (MP) in the United Kingdom from 1875 to 1891, Leader of the Home Rule League from 1880 to 1882, and then of the Irish Parliamentary Party from 1882 to 1891, who held the balance of power in the House of Commons during the Home Rule debates of 1885–1886. He fell from power following revelations of a long-term affair, and died at age 45.

Born into a powerful Anglo-Irish Protestant landowning family in County Wicklow, he was a land reform agitator and founder of the Irish National Land League in 1879. He became leader of the Home Rule League, operating independently of the Liberal Party, winning great influence by his balancing of constitutional, radical, and economic issues, and by his skilful use of parliamentary procedure.

Brittas Bay (Irish: Cuan an Bhriotáis) in County Wicklow, Ireland is a 4 kilometres (2.5 mi) stretch of beach on the Irish Sea coast, about 12 kilometres (7.5 mi) south of Wicklow.

The River Slaney (/ˈsleɪniː/; Irish: An tSláine) is a large river in the southeast of Ireland. It rises on Lugnaquilla Mountain in the western Wicklow Mountains and flows west and then south through counties Wicklow, Carlow and Wexford for 117.5 km (73 mi), before entering St George's Channel in the Irish Sea at Wexford town. The estuary of the Slaney is wide and shallow and is known as Wexford Harbour. The catchment area of the River Slaney is 1,762 km. The long-term average flow rate of the River Slaney is 37.4m/s

Towns that the Slaney runs through include Stratford-on-Slaney, Baltinglass, Tullow, Bunclody, Enniscorthy and Wexford. The river is crossed by 32 road bridges and one railway bridge.

The Wicklow Mountains (Irish: Sléibhte Chill Mhantáin, archaic: Cualu) form the largest continuous upland area in Ireland. They occupy the whole centre of County Wicklow and stretch outside its borders into the counties of Dublin, Wexford and Carlow. Where the mountains extend into County Dublin, they are known locally as the Dublin Mountains (Sléibhte Bhaile Átha Cliath). The highest peak is Lugnaquilla at 925 metres (3,035 feet).

The mountains are primarily composed of granite surrounded by an envelope of mica-schist and much older rocks such as quartzite. They were pushed up during the Caledonian orogeny at the start of the Devonian period and form part of the Leinster Chain, the largest continuous area of granite in Ireland and Britain. The mountains owe much of their present topography to the effects of the last ice age, which deepened the glens and created corrie and ribbon lakes. Copper and lead have been the main metals mined in the mountains and a brief gold rush occurred in the 18th century.Several major river systems have their source in the mountains, such as the Liffey, Dargle, Slaney and Avoca rivers. Powerscourt Waterfall is the second tallest in Ireland at 121 metres (397 feet). A number of these rivers have been harnessed to create reservoirs for drinking water for Dublin and its surroundings.

County Carlow (/ˈkɑːrloʊ/ KAR-loh; Irish: Contae Cheatharlach) is a county located in the Southern Region of Ireland, within the province of Leinster. Carlow is the second smallest and the third least populous of Ireland's 32 traditional counties. Carlow County Council is the governing local authority.

The county is named after the town of Carlow, which lies on the River Barrow and is both the county town and largest settlement, with over 40% of the county's population. Much of the remainder of the population also reside within the Barrow valley, in towns such as Leighlinbridge, Bagenalstown, Tinnahinch, Borris and St Mullins. Carlow shares a border with Kildare and Laois to the north, Kilkenny to the west, Wicklow to the east and Wexford to the southeast.

Vartry Reservoir (Irish: Taiscumar Fheartraí) is a reservoir at Roundwood in County Wicklow, Ireland. The water is piped from Vartry to a large open service reservoir in Stillorgan in the southern suburbs of Dublin. The reservoir is operated by Irish Water.
