Type Of SiteSTONE QUARRY
PeriodPost Medieval
DescriptionModern quarrying started in Nant Gwrtheyrn shortly after 1850 to supply granite setts for paving and construction work in large cities. Three quarries were opened - Cae'r Nant (NPRN 40562), Porth y Nant and Carreg y Llam (NPRN 40533). Ships were loaded regularly from purpose built jetties, carrying setts to Liverpool, Manchester and Birkenhead. In 1878, the settlement of Porth y Nant (NPRN 33025) was established for the quarry workers and their families. Remains of Porth y Nant quarry include buildings, a tramway incline and jetty.
