DENBIGH (Dinbych), municipal borough, market and county town of Denbighshire, Wales, on a branch of the L.M.S.R. Pop. 7,249. The name suggests an early fortification Din in Dinbych means a fort and the pre-Norman fort was called Castell caled fryn yn Rhos, or "the castle of the hard hill in Rhos." Denbigh castle was built, in Edward I.'s reign, by Henry de Lacy, earl of Lincoln, from whom the town received its first charter. The outer wall is nearly a mile round. The castle was given to the Mortimers and to Leicester under Edward III. and Elizabeth respectively. In 1645, after the defeat of Rowton Moor, Charles I. found shelter here. The castle long resisted the Parliamentarians. There are ruins of a Carmelite priory, dating from the 13th cen tury ; a Bluecoat school (1514) ; a free grammar school (15 2 7) ; an orphan girl school (funds left by Thomas Howel to the Drapers' Co., in Henry VII.'s reign); the town hall (built in 1572 by Robert Dudley, earl of Leicester, enlarged and restored in 1780) ; an unfinished church (begun by Leicester), and the old parish church of St. Marcella. The industries are mainly agri cultural with a little quarrying. The borough of Denbigh has a separate commission of the peace, but no separate court of quarter sessions. Near Denbigh, at Bodelwyddan, etc., coal is worked.
