Y Felinheli
Y Felinheli, formerly known in English as Port Dinorwic, is a village, community and electoral ward close to the Menai Strait 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 origins in two hamlets, 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 as well as offered its name to the settlement. The location was greatly agricultural till the location was changed by slate quarrying in the 19th century. A new dock was built in 1828 when lime was removed at Brynadda and slate and lime were filled and culm (coal dust or anthracite slack) was brought in to terminate the lime kilns. The owners of the Vaynol Estate, the Assheton Smiths, possessed the majority of the land in Y Felinheli and also established the Dinorwic Quarry in the late 18th century, They additionally constructed the harbour to export slate delivered to the quay by the Dinorwic Railway, a narrow gauge train that was consequently changed by the Padarn Railway. Industrial growth offered Y Felinheli (Felin-hely, 1838) the different name Port Dinorwig or Port Dinorwic.
