A recent discovery of mine is 'Llwyn-Ysgaw' water mill near the village of Y Ferwig, near Cardigan.
The road is in fact a small road off the beaten track hence not seeing it before!
It is a later 19th Centaury iron overshot twelve foot waterwheel made by T. Thomas of Cardigan in rubble stone wheel pit.
Timothy Thomas was a maker of many kinds of agricultural machinery and this wheel was probably made after his move from the Mwldan Engineering Works in Cardigan to the Bridge End Foundry in the same town in 1854.
It is a Grade II Listed monument managed by the National Trust; however, I have to say it was very overgrown even though it is winter still.
There are some remains of the stone buildings in the undergrowth behind the wheel although not much is left.
