Y Felinheli
Y Felinheli, formerly known in English as Port Dinorwic, is a town, community as well as electoral ward next 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 2 hamlets, Tafarngrisiau near St Mary's Church as well as Aberpwll to the north-east where there was a mill on the Afon Heulyn. The mill was reconstructed closer to the sea in 1633 as well as gave its name to the settlement. The area was mostly agricultural till the location was changed by slate quarrying in the 19th century. A brand-new dock was built in 1828 when lime was removed at Brynadda and slate and lime were packed and also culm (coal dirt or anthracite slack) was brought in to fire the lime kilns. The owners of the Vaynol Estate, the Assheton Smiths, owned most of the land in Y Felinheli and also developed the Dinorwic Quarry in the late 18th century, They also built the harbour to export slate transferred to the quay by the Dinorwic Railway, a narrow scale railway that was consequently changed by the Padarn Railway. Industrial expansion gave Y Felinheli (Felin-hely, 1838) the alternate name Port Dinorwig or Port Dinorwic.
