Craig-y-Nos Castle - Penwyllt

Penwyllt

The industrial development of the village of Penwyllt, came as a result of the need for quicklime in the industrial processes in the lower Swansea Valley. Quarrying clay from the surrounding hills, in total there were fifteen lime kilns turning it into quicklime within the parish of Penwyllt:

• Craig-y-nos: two lime kilns created in the railway age, dated 1878.
• Pen-y-Foel: a bank of four kilns erected in around 1863 to 1867 by, it is thought, the Brecon Coal & Lime Co. There is a loading bank for railway wagons in front of the kilns.
• Twyn-disgwylfa: Built by Joseph Claypon between 1836 and 1842, this bank of seven kilns has been largely destroyed by quarry tipping. Only one draw arch can now be seen.
• Twyn-y-ffald: The 1825 and 1827 kilns built by Joseph Claypon have been largely demolished, although the single draw arch can still be seen.
