Killiney, Coastal residential area in Dún Laoghaire-Rathdown, Ireland.
Killiney is a residential area along Dublin Bay featuring beaches and walking trails on elevated ground above the water. The settlement spreads along the coastline with open spaces and green areas interspersed among the homes.
The settlement started in the 11th century with a church that shaped the early community. By the 1800s, it transformed into a popular residential place as people sought homes near the city.
The name comes from an old religious settlement linked to the daughters of a local leader, a connection that residents still recognize in the area's identity. This heritage has shaped how people relate to the place over centuries.
The DART train and bus route 59 connect the area throughout the day to Dublin city center and surrounding towns. Visitors can arrive easily by public transport and move around without a car.
An obelisk on Killiney Hill was built in the 1740s as a work project during a severe famine to give people employment. The monument still stands today and offers wide views across the bay from the top.
