Silsean is in the central sector, at the western edge, of the Wicklow Mountains, in County Wicklow, Ireland. Silsean is on a small massif alongside Moanbane which lies between the Blessington lakes (or Poulaphouca Reservoir), and the major massif of Mullaghcleevaun .__NOTOC__
The village of Ballyknockan exists on the northern slopes of the hill. Bonfires were lit on the hill in former times to celebrate events, as recorded by Barry Kinane in "Welcome to the Granite City: A Social History of Ballyknockan": Dr. Walsh, Archbishop of Dublin, visited the parish of Blackditches in July 1907 to administer confirmations... The Archbishop was held in high regard by the men of Ballyknockan since he helped resolve a worker dispute in 1885. The night the Archbishop departed Ballyknockan was described in the Wicklow Notes in vivid detail. The Valley of the Kings River was a natural amphitheatre of rolling hills illuminated by bonfires. An immense beacon was erected by the men of Ballyknockan on Garry Ou Hill (Silsean), and it could be seen as far out as the sea.
