Y Felinheli
Y Felinheli, formerly recognized in English as Port Dinorwic, is a town, community and electoral ward beside the Menai Strait in between Bangor and Caernarfon in Gwynedd, north-west Wales. The population of the town was 2,284 at the 2011 Census. Y Felinheli has its beginnings in two hamlets, Tafarngrisiau near St Mary's Church and 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 provided its name to the settlement. The area was mainly agricultural until the area was transformed by slate quarrying in the 19th century. A new dock was built in 1828 when lime was removed at Brynadda and slate and also lime were loaded and also culm (coal dust or anthracite slack) was generated to terminate the lime kilns. The owners of the Vaynol Estate, the Assheton Smiths, possessed a lot of the land in Y Felinheli and also created the Dinorwic Quarry in the late 18th century, They likewise developed the harbour to export slate transported to the quay by the Dinorwic Railway, a narrow gauge railway that was subsequently replaced by the Padarn Railway. Industrial expansion gave Y Felinheli (Felin-hely, 1838) the different name Port Dinorwig or Port Dinorwic.
