Ty Coch Water Powered Carpenters Workshop in Pontdolgoch, Caersws SY17 5NJ
A fully intact, water powered working victorian carpenters workshop of national importance, listed at Grade 2* (putting it in the top 7% of all listed buildings).
The mill is an important part of the heritage of Wales, considered unique by CADW and the Times listed it as one of the top 10 working MIlls in the UK.
The Mill was used by the Owen family making wooden cart wheels right up to the 1990’s and is a traditional carpenter workshop which included coffin making. It is powered by a powerful overshot water wheel made in Aberystwyth.
Open on Saturday 10th May 10am – 4pm.
Ty Coch is in Pontdolgoch beside the A470 on the right just over the River Carno bridge. That is just after E George, the agricultural merchants on the other side of the road. There is ample parking and teas will be served.
Trericket Mill, Erwood, Builth Wells, LD2 3QT
A large Mill and Mill House that stands immediately below a cliff. The mill leat came from the weir at cliff-top height and reached the millwheel by a short aqueduct. In 1923, the millwheel was replaced by a turbine and the pitwheel was replaced by a smaller, bevilled wheel connecting the turbine to the spurwheel. The wallower is now redundant. Sadly the turbine is now split so is also redundant. Today the Mill house extends into the Mill so bookshelves and beds now nestle among the gears that drive the millstones and the wheels which power belt-driven machines such as the dresser.
The mill is on the west side of the A470 between Erwood and Llyswen. NGR SO 11264 41406
Open on both Saturday and Sunday but strictly by appointment only. Please contact Pam Martin 07976 797107. Please note there is limited parking space.

Felin-Rhyd-Hir, Efailnewydd, Pwllheli, LL53 8TN
Felin-Rhyd-Hir is a two-storeyed, stone-built water-powered corn mill under a pitched slated roof. The composite overshot waterwheel remains in place on the north west gable wall, and there are two pairs of millstones which, it is hoped, will be able to work in future.
The mill was supplied by a pond to the north of the mill, fed from the Afon Rhyd-Hir via a 1.7 km long leat which also captured the tailrace water from Melin Llannor.
The owners have carried out an extensive restoration project with a working waterwheel.
