Ardnacrusha (ga|Ard na Croise) is a village in County Clare, Munster, Ireland, located on the northern bank of the River Shannon. By road, it is north of Limerick. The name derives from the phrase Ard na Croise meaning "the height of the cross", due to a large cross marker placed there in 1111 to mark the boundary of the Diocese of Limerick.[1]
In 2002, the population of the village was 926. [2]
Ardnacrusha is located near the site of the Ardnacrusha power plant, constructed in the 1920s.[1] By 1935, it was producing 80 per cent of Ireland's electricity.[3]
