Glendalough comes from the Irish “Gleann da locha”, meaning the Glen of two Lakes.
Wicklow Mountains National Park is situated just south of Dublin. The park covers 20,000 hectares of mountain scenery, and many roads cross through it. The most popular location for visitors to the National park is the scenic and historic valley of Glendalough.
Wikipedia: Glendalough is a glacial valley in County Wicklow, Ireland, renowned for an Early Medieval monastic settlement founded in the 6th century by St Kevin. From 1825 to 1957, the head of the Glendalough Valley was the site of a galena lead mine.
