Christmas Mad Friday tonight in Denbighshire, UK

Denbighshire ( DEN-bee-shər, -⁠sheer; Welsh: Sir Ddinbych; [ˌsiːr ˈðɪnbɨχ]) is a county in the north-east of Wales. Its borders differ from the historic county of the same name. This part of Wales contains the country's oldest known evidence of habitation – Pontnewydd (Bontnewydd-Llanelwy) Palaeolithic site has Neanderthal remains of some 225,000 years ago. 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 is bounded by coastline to the north and hills to the east, south and west. The River Clwyd follows a broad valley with little industry: crops appear in the Vale of Clwyd and cattle and sheep in the uplands. The coast attracts summer visitors; hikers frequent the Clwydian Range, part of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty. Llangollen International Musical Eisteddfod takes place each July.
