Llangollen is a small town and community in Denbighshire, north-east Wales, situated on the River Dee and on the edge of the Berwyn mountains.Llangollen takes its name from the Welsh llan meaning “a religious settlement” and Saint Collen, a 6th-century monk who founded a church beside the river. St Collen is said to have arrived in Llangollen by coracle. As there are no other churches in Wales dedicated to St Collen, it is possible that he may have had connections in Colan in Cornwall, and Langolen in Brittany.Situated above the town to the north is Castell Dinas Brân, a stronghold of the Princes of Powys. Beyond the castle is the limestone escarpment known as the Eglwyseg Rocks. The outcrop continues north to World’s End in Wrexham. The area nearest the castle is the Panorama Walk, and a monument to poet I.D. Hooson from the village of Rhosllannerchrugog can be found there.Valle Crucis Abbey was established in Llangwestl in about 1201, under the patronage of Madog ap Gruffydd Maelor of Castell Dinas Brân.
