The name “Llangywer” is very familiar to most Welsh people from the famous folk song ‘Ffarwel i Blwy’ Llangywer’. The parish probably took its name from Saint Cywair, and one of her wells is located where Ffynnon Gywer farm is to be found today. According to the folk tale she also had another well, but someone forgot to replace the stone over that well and it overflowed, drowning a wide area and forming Llyn Tegid (the name of the lake at Bala) as we know it today. The parish can boast of its scenic location on the shores of the Lake and facing the Arenig mountain range. Although it is a large parish extending from the borders of Montgomeryshire to the Lake and from the Gyrn to Caletwr, its population is sparse with most people living on hillside farms or in in the small villages of Rhosygwaliau and Llangywer.
