County Dublin

County Dublin is a former administrative division in Leinster on the eastern coast of Ireland, now split into four separate local government areas. The territory runs from the airport in the north down to Dalkey Bay in the south, including both the city center and coastal villages alongside suburban neighborhoods.

The territory originated in the 12th century under Norman rule as one of the first administrative divisions in Ireland. In 1994 it was dissolved into four separate councils to better manage the growing population.

The name comes from the Irish Dubh Linn, meaning black pool, referring to a natural hollow in the ground. Visitors today notice Georgian terraced houses with colorful doors lining many streets, giving the area a sense of order and elegance.

Visitors can orient themselves along the coastal paths by the bay or use the many parks as landmarks. The four councils operate independently, which means public facilities and opening times may vary depending on the area.

The boundary between the four present-day councils sometimes runs through the middle of residential areas, so neighbors may belong to different administrations. At some crossroads you move from one council area to another without noticing it at first glance.
