Pwllheli is a neighborhood and the major market town of the Llyn Peninsula (Welsh: Penrhyn Llyn) in Gwynedd, north-western Wales. It had a population of 4,076 in 2011 of whom a big proportion, 81%, are Welsh speaking. Pwllheli is the place where Plaid Cymru was founded. It is the birth place of the Welsh poet Sir Albert Evans-Jones (bardic name Cynan). Pwllheli has a series of stores and also various other solutions. As a neighborhood railhead with a market every Wednesday, the town is a gathering point for the population of the entire peninsula. For years a holiday camp run by Butlins ran a few miles from Pwllheli at Pen-y-chain. During the 2nd World War it came to be a naval camp, HMS Glendower, and it operated a medical facility for damaged servicemen at Brynberyl on the Pwllheli to Caernarfon roadway 2 miles out of town. After the war, Butlins re-established the holiday camp. The camp, now relabelled Hafan y Môr ("Haven of the Sea"), has actually been redeveloped as well as is currently run by the Haven team.
