Glendalough Woollen Mills was founded fifty years ago by jeweller, Joe O'Neill. He started the shop as a means to showcase his jewellery inspired by the beauty of the ancient monastic city of Glendalough. Joe had an interest in allowing other local craft makers to showcase their products, and thus Glendalough Woollen Mills was born. Today the shop sells a wide array of products made and designed in Ireland and is still managed by Joe and his wife, knitwear designer, Martha O'Neill. Glendalough Woollen Mills has sister shops that can be found in both County Clare and County Tipperary.
