Places to See | Co. Down, Northern Ireland.
The Silent Valley is a Mountain Park situated in the high Mournes in an area of Outstanding Natural Beauty features a dam ringed by dramatic Mountain panoramas and the famous Mourne wall located in the U-shaped valley of the Kilkeel river.
Nestled between the granite peaks of Slieve Binnian and Slievenagloghy, Silent Valley has served as the principal water source for Belfast since the completion of its reservoir in 1933.
The history of the long and hazardous hours endured by the dam builders is a fascinating one, and the forklore associated with the men who worked in the compression shafts has become an integral part of the Valley’s story. An account of life during the construction of Silent Valley is on display in the information centre.
