CORWEN ("the white choir"), a market town of Merioneth shire, Wales, on the Dee, a little below its confluence with the Alwen, om. W. of Llangollen. Pop. (1921) 2,69o. The Berwyn range rises steeply to the south, so that the town is confined between wooded cliffs and the swift-flowing Dee. Telford's Holy head road through the Bala cleft, the successor of hillside tracts of prehistoric date, opens up the district to tourists. The town is also a favourite angling centre. There are many associations with the Welsh chieftain, Owain Glyn Dwr; it was here that he had his headquarters and assembled his forces before the battle of Shrewsbury (1403). The much restored parish church dates in part from the i3th century. At Corwen the L.M.S.R. from Den bigh joins the G.W.R. from Llangollen to Dolgelley.
