Citywest is a business park and golf resort in the Saggart area, just north and northwest of Saggart village in South Dublin. The nearest major town is Tallaght. The business park has developed a modest residential population in recent years. The River Camac passes north of the business park, and two of its tributaries pass through it.
Originally a greenfield site north of Saggart village, west of Tallaght, and largely south of the Naas dual carriageway (now the M7 / N7), the combined Citywest concepts were launched by Irish construction firm Davy Holdings, who began building of the business park in the early 1990s, and Jim Mansfield, who drove the hotel and leisure aspects.
A substantial golf course, for a time Citywest and Hibernian Golf Club, now just Citywest Golf Resort, was laid-out. The large Citywest Hotel, with over 1,700 rooms, was built adjacent to this. The hotel, golf resort and related developments were placed in receivership in mid-2010.
Following the opening of the original business park the N82 National road joining the N81 to the Naas dual carriageway was re-routed through the campus. It previously passed through the village of Saggart itself.
Several major businesses moved to the business park, notably eircom, mobile operator Meteor, and Independent News and Media, and branch offices of Xilinx, Unilever, Pfizer, SAP and Roche.
