Coolock () is a large suburban area, centred on a village, on Dublin city's Northside in Ireland. Coolock is crossed by the Santry River, a prominent feature in the middle of the district, with a linear park and ponds. The Coolock suburban area encompasses parts of three Dublin postal districts: Dublin 5, Dublin 13 and Dublin 17.
The extensive civil parish of Coolock takes in the land between the Tonlegee Road (as far as Donaghmede) and the Malahide Road, as well as the lands on either side of the Malahide Road between Darndale and Artane, and the lands either side of the Oscar Traynor Road on the approach to Santry.
Coolock is also the name of the historical barony which accounts for most of north Dublin city, from the coast as far as Phoenix Park, and stretching north as far as Swords.
Coolock has a history dating back over 3,500 years – a Bronze-Age burial site in the area dates back to 1500 BC. Up until the early 1800s, a series of raths or mounds were present in the area, and were later flattened. One remains on the grounds of the Cadbury factory. The settlement grew up around a small early-Christian church. An early stone cross remaining near the Church of Ireland St John the Baptist Church associated with an early church of St Brendan the Navigator. A Catholic church, St. John's, was later built in the area. During Norman times, the area was owned by the Nugent family. It was later owned by the monastery of Duleek, and later the Earl of Drogheda.
A large Roman chapel was recorded there in 1780, and in 1831 the chapel was rebuilt with the thatched roof replaced with slates at a cost of ã500. The area was still primarily agricultural, supplying Dublin city. In the 1600 and 1700s, quarries were also opened. around the turn of the 1800s, a number of large houses were built, including Coolock House. Coolock House was the home of the chemist, William Callaghan, who was the adoptive father of the foundress of the Sisters of Mercy, Catherine McAuley. Coolock House later became a convent.
Coolock remained a small village until the 1950s, with lands around the village being further developed over time, notably Bonnybrook and Kilmore West, between which a new centre to the area formed. A factor in this expansion was the construction of large housing estates by the Dublin Corporation. At one time the old village was on the Malahide Road but that road was diverted and now passes slightly to the east of the village; in the meantime, a secondary hamlet, Newtown Coolock, developed further north. Between 1961 and 1966, the population of Coolock increased by 91.8%.
Later in the 20th century, lands in the north of Coolock were developed to form the new districts of Darndale and Priorswood.
Coolock lies on either side of the valley of the Santry River and includes a diversion from the little Naniken River. It is a relatively flat area a little above sea level, with a linear park around the Santry, and small green areas scattered through residential developments.
Coolock lies at the centre of the majority working-class Northside suburbs such as Kilbarrack, Donaghmede and the Edenmore part of Raheny, and itself includes localities such as Ayrfield, Bonnybrook, Darndale, Priorswood, Greencastle and Kilmore West. As with other large suburban areas, such as Tallaght or Swords, there is no legal definition for Coolock, and so no definitive population figures, but it is one of Dublin's largest residential areas. It is crossed by the Oscar Traynor Road, running from the Malahide Road to Santry, and named for the War of Independence politician, later long-serving minister, Oscar Traynor. The majority of Coolock, excluding Ayrfield, was built-up by the city authority, Dublin Corporation, as part of a programme of the phased inner-city slum clearance (between the 1950s and 1980s).
The permanent Traveller halting site estates of Cara Park and Dominick Park, found in the Belcamp area along the N32, are among the largest halting site facilities provided by local authorities in Ireland. They contain an adult education centre and pre-school facilities and are located beside Dominick Park.
Public parks in the area include the Santry River Linear Park and in Bonnybrook the Stardust Memorial Garden which is dedicated to the 48 people who lost their lives in the Stardust nightclub. Parnells GAA club is based in Coolock village.
Coolock is also a centre of local government activity, with a Dublin City Council major centre, NEAR FM community radio station, a Health Services Executive centre and a recycling centre.
Localities and housing developments in the Coolock area include:
Located between Donaghmede and Coolock is Clare Hall, a later housing estate, which includes a small shopping precinct, and the larger Clarehall Shopping Centre.
The area has a number of roads named after the 1969 Moon landing, including Tranquility Grove (after Tranquility Base), Eagle Park (Lunar Module Eagle), Apollo Way (Apollo 11), Armstrong Walk (Neil Armstrong) and Aldrin Walk (Buzz Aldrin).
Coolock has given its name to religious divisions over a long period, and the primary historical ones are discussed at Parish of Coolock (Roman Catholic), and (from the Act of Supremacy), Parish of Coolock (Church of Ireland). Both Catholic (multiple) and Church of Ireland buildings stand within the area today. In the Catholic divisions, additional parishes today include Bonnybrook and Ayrfield (encompassing the Greenwood estate).
National (primary) schools in the area include St. Pauls Junior and Senior National School (Ayrfield) and St. Francis Junior and Senior Schools (Priorswood).
Secondary schools include Chanel College (a boys school and adult education centre founded in 1955), the Donahies Community School (founded 1977), Coláiste Dhúlaigh Post Primary (a co-ed secondary school in Coolock), and Mercy College (a voluntary, Catholic girls secondary school). The now-defunct Catholic Belcamp College secondary school operated in nearby Balgriffin from 1893 to 2004.
Coláiste Dhúlaigh College of Further Education provides third-level courses (QQI, BTEC and FETAC).
The outskirts of Coolock host several factories and industrial estates. Cadbury Ireland has been manufacturing chocolate products since 1957, for both the Irish market and for export. The nearby Tayto Crisps factory manufactured snack foods until it closed in 2005.
Notable retail facilities include Northside Shopping Centre, Ireland's first covered shopping centre, situated near accesses to the M1 and M50, with more than 70 outlets and a city council swimming pool.
Famous historical figures linked to the area included Henry Grattan of Belcamp Park, and the novelist Charles Lever.
The Coolock area was featured extensively during location shooting for the 1991 film The Commitments, directed by Alan Parker and starring a mainly unknown cast at the time.
Coolock, which is not crossed by any rail systems, is serviced by main roads, including the N32 and Oscar Traynor Roads which link to the M1, and by the following Dublin Bus routes:
