Killiney () is an affluent seaside resort and suburb in Dún Laoghaire–Rathdown, Ireland. It lies south of neighbouring Dalkey, east of Ballybrack and Sallynoggin and north of Shankill. The place grew around the 11th century Killiney Church, and became a popular seaside resort in the 19th century. It is part of the Dáil Éireann constituency of Dún Laoghaire. Amenities Killiney Hill Park was opened in 1887 as Victoria Hill, in honour of Queen Victoria's 50 years on the British throne. The park has views of Dublin Bay, Killiney Bay, Bray Head and the mountain of Great Sugar Loaf (506 m), stretching from the Wicklow Mountains right across to Howth Head. The Park's topography is steep, and its highest point, at the obelisk, is 170 metres above sea level. Other attractions include Killiney Beach, Killiney Golf Club, a local Martello Tower, and the ruins of Cill Iníon Léinín, the church around which the original village was based. The coastal areas of Killiney are often compared to the Bay of Naples in Italy. This comparison is reflected in the names of surrounding roads, like Vico, Sorrento, Monte Alverno, San Elmo and Capri. On clear days, the Mourne Mountains of County Down can be seen. Killiney Hill Park was once part of the estate of Killiney Castle, now a hotel. Since early 2010, a pod of bottlenose dolphins has been seen occasionally in Killiney Bay. There is a small shopping centre in Killiney and the village contains a newsagent and a pub, the Druid's Chair. There is a hotel, Fitzpatrick's Castle Hotel. History The village of Killiney takes its name from the site of the Nuns' Abbey. Leinin, a local chieftain, and his seven daughters converted to Christianity, and together they went on to found a monastic community at what is now Marino Avenue West. Today the family are commemorated in the stained-glass windows of the Church of St Alphonsus and Columba in Ballybrack, just a couple of minutes' walk away. Although the establishment of the first church dates back to the sixth century, its current roofless ruin dates from the 11th century. This tiny chapel on Marino Avenue West marks the historical centre of Killiney village, and can still be viewed today. For many centuries the major part of the district was the property of the Talbot de Malahide family, some of the original followers of the 1170 Norman invasion. The obelisk
