Location Tallaght is centred 13 km (8 miles) southwest of
Dublin city, near the foothills of the
Wicklow Mountains. While there is no formal definition as such, it can be described as beginning southwest of
Templeogue, running west towards
Saggart, southwest towards the mountain areas of Bohernabreena, Glenasmole and Brittas, southeast towards
Firhouse, and to the southern edges of
Clondalkin in the northwest and
Greenhills in the northeast. It lies outside the
M50 Dublin orbital motorway, and in effect forms an irregular circle on either side of the
N81 Dublin-Blessington road. The suburban villages of
Saggart and
Rathcoole, and the Citywest campus, with growing amounts of housing, lie west of Tallaght, along with the Air Corps aerodrome at
Baldonnel. There is also still considerable open land, some still actively farmed, in this direction. The village core of the district is located north of, and near to, the
River Dodder, and several streams flow in the area. The Jobstown Stream or Tallaght Stream (a tributary of the Dodder), approaches from the west, and takes in at least one tributary, the Killinarden Stream from the south, near the N81. Bus routes to Dublin city centre include the 27 (via
Jobstown and
Tymon Park), 56a (The Square, Springfield, Fettercairn and Kingswood), 65 (The Square, Tallaght Hospital, Tallaght Village and Balrothery), 65b (Killinarden Heights, Kiltipper Road, Aylesbury, Old Bawn, Firhouse and Ballycullen), 77a (
Blessington, Killinarden Heights, The Square, Tallaght Hospital, Tallaght Village,
Oldbawn, Balrothery and Tymon Park), 82 (Poolbeg to Kiltipper) and F1 (IKEA to The Square). Former routes include the 75 (The Square, Rathfarnham, Ballinteer, Dundrum, Stillorgan, and Dún Laoghaire) and 175 (Citywest, Dundrum and UCD). Since November 2023, they have been withdrawn and largely replaced with the new S6 and S8 routes. While the proposed
"Metro West" metro line was projected to serve Tallaght, this proposed project was shelved in 2011.
Population South Dublin County Council stated in 2003 that the population of Tallaght
and environs was just under 73,000. The population of the historic
civil parish of Tallaght, including areas such as Templeogue, Ballyroan, and wide areas of mountain as far away as Castlekelly, is 101,059.
Districts "Greater Tallaght" comprises Tallaght village and a range of areas that were formerly small settlements (Jobstown, Old Bawn, Kilnamanagh) and rural townlands. The original village of Tallaght lies west of the
Tallaght Bypass (N81). It stretches east–west from Main Road and Main Street to the Abberley Court Hotel at the end of High Street and encompasses the Village Green shopping plaza, Tallaght Courthouse, Westpark, and many shops, and restaurants and banks. It also houses Tallaght Youth Service, Tallaght's first newspaper printing house the
Tallaght Echo, and (formally) Tallaght Community Arts Centre. The area's
Institute of Technology, Saint Mary's Priory, and Saint Maelruain's Church are located in the historic quarter of Tallaght village. The newer "town centre" lies immediately to the south across the
Belgard Road, encompassing Belgard Square, the main shopping complex (known as
The Square also known as the Pyramid), the
Luas Red Line terminus, Tallaght Hospital (including the National Children's Hospital), County Hall, the Civic Theatre, South Dublin County Library, Rua Red Arts Centre, and several bars, restaurants and hotels. To the northeast of the village lies the Tymon North / Balrothery area, which comprised rural townlands until the 1970s. This district includes estates such as Bancroft, Balrothery,
Glenview, Castle Park, Saint Aongus, Tymon, Bolbrook and Avonbeg. These areas are home to several sporting facilities, including the
National Basketball Arena, a fitness centre, two swimming pools, an athletics track, and an astroturf football facility.
Tymon Park is watered by the
River Poddle and borders
Greenhills and
Templeogue. It contains sporting grounds, ponds, Coláiste De Hide and a large playground at the Tymon North entrance. Old Bawn, formerly a small village in its own right, is immediately south of the village, bordered by
Sean Walsh Memorial Park (also locally called
Watergate). To the east of Old Bawn, estates include Home Lawns, Mountain Park, Millbrook Lawns and Seskin View. To the south and southwest of the village lie Ellenborough, Aylesbury, and Killinarden (the latter comprising the residential areas of Deer Park, Cushlawn, Donomore, Killinarden Estate and Knockmore). Beyond these are rural lands, running towards the Wicklow Mountains. In the northwest is Belgard Green, with Belgard Heights (built 1974) to the north. Half of Kingswood is served by Clondalkin Garda Station. Kingswood and Belgard Heights are adjacent to
Clondalkin, while Kilnamanagh is situated beside Greenhills and south-west of
Walkinstown and
Crumlin.
Tallaght Theatre is situated along Greenhills Road. Virginia Heights and Springfield are close to the area's centre, and further west of the town centre is the former hamlet of
Jobstown, which is divided from Central Tallaght via the N81 and the Cheeverstown Road, Jobstown now has dense housing estates, and also the previously rural areas of Kiltalown, Brookfield and Fettercairn.
