The pyramid on Killiney Hill is very close to the obelisk, but a little hidden behind gorse hedges. It was built in 1852 by Robert Warren, the then owner of the estate. Locals also refer to the pyramid as “Wishing Stone”. According to their interpretation, a wish comes true when one circles all levels of the pyramid, climbs the uppermost pinnacle and while looking towards St. Begnet’s Oratory on Dalkey Island expresses his wish. Whether this is really the case cannot yet be conclusively confirmed. An indisputable fact, however, is that you have a first-class view over Dublin Bay from the pyramid.
