DENIO (DENEIO), a parish, in the hundred of GAFLOGION, county of CARNARVON, NORTH WALES, including the town of Pwllheli, and containing 2091 inhabitants. The living is a perpetual curacy, annexed to the vicarage of Llannor, in the archdeaconry and diocese of Bangor. The church, dedicated to St. Beuno, is situated about half a mile to the north of Pwllheli; but being very small and in a state of great dilapidation, it is in contemplation shortly to erect a new church at that town, where all ecclesiastical rites, except that of burial, will be performed: the present ancient structure is built somewhat in the form of the Roman letter L. The average annual expenditure for the support of the poor, including those of the town of Pwllheli, amounts to £511. 11. See PWLLHELI.
