Denbighshire is a county in north-east Wales, whose borders differ from the historic county of the same name. It is the part of Wales known to have been inhabited longest – Pontnewydd (Bontnewydd-Llanelwy) Palaeolithic site has Neanderthal remains of 225,000 years ago. Its several castles include Denbigh, Rhuddlan, Ruthin, Castell Dinas Bran and Bodelwyddan. St Asaph, one of Britain's smallest cities, has one of its smallest Anglican cathedrals. Denbighshire has coastline to the north and hills to the east, south and west. The River Clwyd creates a broad fertile valley down the centre of a mainly rural county with little industry. Crops are grown in the Vale of Clwyd and cattle and sheep reared in the uplands. The coast attracts tourists; hikers frequent the Clwydian Range, which forms an Area of Outstanding Natural Beauty with the upper Dee Valley. Llangollen hosts the Llangollen International Musical Eisteddfod each July.
