Glendalough
Early Medieval Monastic Settlement Founded By St Kevin In The 6th Century, In A Glacial Valley Of Two Lakes Inside Wicklow Mountains National Park · Laragh, Wicklow
Glendalough (Gleann Da Loch, the valley of two lakes) is an early medieval monastic settlement in the Wicklow Mountains, about an hour south of Dublin. St Kevin came here as a hermit in the 6th century and the monastery that grew around him became one of the great religious centres of early Ireland, a place of pilgrimage for centuries. What survives is a cluster of stone ruins in a glacial valley: a near-complete round tower about 30 m high, the roofless cathedral, St Kevin's Church with its little stone belfry, a monastic gateway and a graveyard of old crosses, with the Lower and Upper lakes and wooded walking trails beyond. The monastic site is free to wander at any hour, and the walks inside Wicklow Mountains National Park range from a flat lakeside stroll to a high loop above the cliffs. The honest caveat: this is one of the most visited places near Dublin, the upper car park fills by late morning at weekends and in summer, coach tours arrive in waves, and rain can close in the valley for days.
