Dalkey Quarry (/ˈdɔːki/ DAW-kee) is a long-disused 19th century granite quarry located on Dalkey Hill in the Dublin suburb of Dalkey, which was used to build several large maritime structures in south Dublin. Since passing into public ownership in the early 20th century and becoming part of Killiney Hill Park, it has become one of the most important rock climbing venues in Ireland, with over 350 graded routes, some of which are amongst the hardest single-pitch rock climbs in the country such as Indecent Assault (E8 6c, one of Ireland's first-ever E8 routes, first ascended in 1995). The climbs are all traditional climbing routes and no bolted sport climbing routes are permitted, although some metal pegs are tolerated on the most extreme routes.
