At the north end of Stoney Road in the corner of a field there is a pool that hides stepped stone slabs. Unambiguous roman engineering on a defunct roman road where in the late C19 the ‘Wern Lane Roman Hoard’ was unearthed. Methodical metal detecting at Treflach Hall has recorded much Roman activity. Romans were famous for their bathing and baths and these cold limestone waters were the best they could get when they started their invasion of Wales.
Fast forward many centuries and bathing was thought to be bad for the health. Treflach Farm pool was the communal destination however when Woodhill was constructed in 1792 Bath Meadow and Bath Wood today hide the remains of a Victorian construction for private bathing for the wealthy. A similar construction can be found in the woods in Morda behind Glentworth.
Treflach Hall had its pool in the yard fed by the waterwheel in pump meadow with a well under the farmhouse from ancient times. Treflach Farm meanwhile constructed an aqueduct from the pool at pump meadow dating back to the time of Thomas Savin [https://en.wikipedia.org/wiki/Thomas_Savin] who was born at Llwn-y-maen) that had a similar construction on the River Morda to power a mill. Treflach Farm then had running water up to the back door of the farmhouse until 1936 when a water ram was installed and the aqueduct was filled in.
