The Irish name Coill Mhór, meaning big forest, refers to the oaks, silver birches, holly and conifers that cover the north shore of Pollacappul Lake, at the foot of Mount Doughrough. A neo-Gothic castle with towers and crenels, built between 1860 and 1867 in Dalkey granite, currently houses a community of Benedictine nuns and a school. The arts and crafts centre sells a wide range of hand-made and hand-decorated Kylemore pottery.
