Y Felinheli
Y Felinheli, previously recognized in English as Port Dinorwic, is a town, area as well as electoral ward beside the Menai Strait between Bangor and also Caernarfon in Gwynedd, north-west Wales. The population of the town was 2,284 at the 2011 Census. Y Felinheli has its beginnings in 2 communities, Tafarngrisiau near St Mary's Church and also Aberpwll to the north-east where there was a mill on the Afon Heulyn. The mill was rebuilt closer to the sea in 1633 and gave its name to the negotiation. The area was mainly agricultural till the area was changed by slate quarrying in the 19th century. A brand-new dock was integrated in 1828 when lime was extracted at Brynadda and also slate and also lime were loaded and culm (coal dust or anthracite slack) was generated to fire the lime kilns. The proprietors of the Vaynol Estate, the Assheton Smiths, possessed a lot of the land in Y Felinheli as well as developed the Dinorwic Quarry in the late 18th century, They also constructed the harbour to export slate transferred to the quay by the Dinorwic Railway, a narrow gauge railway that was consequently replaced by the Padarn Railway. Industrial expansion provided Y Felinheli (Felin-hely, 1838) the alternate name Port Dinorwig or Port Dinorwic.
