This is Glendalough, the monastery founded by St Kevin in the 6th century that became one of the great centres of learning in early Christian Ireland. Carved by grinding glaciers during the last Ice Age, the valley of Glendalough is a sweeping expanse that combines unbelievable natural beauty with utter serenity. The Glendalough Valley is located in the Wicklow Mountains National Park and has many attractions to entice visitors, from its world famous Monastic Site with Round Tower to its scenic lakes and valleys, as well as a selection of walks and trails in the area including The Wicklow Way.
