Dwyfor
Dwyfor was one of the five local government districts of Gwynedd, Wales from 1974 to 1996, covering the Llŷn peninsula. Its council was based in Pwllheli. It was formed on 1 April 1974 as a successor to the borough of Pwllheli, the urban districts of Criccieth and Porthmadog, along with Llŷn Rural District, and part of Gwyrfai Rural District, all previously in the administrative county of Caernarfonshire. It was named after the river Dwyfor. Dwyfor was notable for being the last stronghold of the Sabbatarian temperance movement in Wales. Under the terms of the Licensing Act 1961, local referendums  prevented the opening of public houses on Sundays until 1982, and a further referendum (on a 9% turnout) reimposed Sunday closing between 1989 and 1996. It was abolished as a district when Gwynedd was reconstituted as a unitary authority on 1 April 1996. It remains in use as an area covered by an area committee of Gwynedd Council.
