The obelisk, known locally as the 'Wishing Stone,' was built by John Mapas to create work for the local poor during a period of extreme cold in 1742.
The park's granite base is part of the Leinster Granite massif, which formed approximately 400 million years ago.
The summit provides a 360-degree panoramic vantage point, allowing for clear views of Bray Head and the Sugar Loaf mountain to the south.
The site was historically part of the Mount Mapas estate before being opened as a public park for Queen Victoria's Jubilee in 1887.
A stone plaque near the summit commemorates the site's original dedication as Victoria Hill.
Killiney Hill Park offers elevated views of the Irish Sea, Dublin Bay, and the Wicklow Mountains from a 153-meter summit. The park features an obelisk constructed in 1742 to provide employment during a famine. Its landscape includes diverse trails through mature woodland and open heathland overlooking the coastal towns of Dalkey and Killiney. The terrain consists of granite outcrops and walking paths that connect to the wider Dalkey Hill area. The park serves as the highest point of the Killiney coastal ridge, marking the southern edge of the Dublin metropolitan area. It functions as a public amenity space managed for biodiversity and recreational access.
