The Domesday Book mentions a mill in Dyserth in 1086 (possibly located at the waterfall), worth 3 shillings. And in 1303-4 there is a record of 64 shillings and 8 pence paid out for timber to repair “the said mill of Dissard which threatened ruin”.

A lease for Dyserth Mill dated 20th October 1795 forbids “ the said Water Corn Grist Mill or any of the premises hereby demised to be converted for Methodists or any other Denomination of Sectaries”. Another document records the right to “harvest watercrowses” from the stream, an early reference to the use of watercress as a foodstuff in North Wales. (Paragraph from Curious Clwyd - A second Photographic Album of Oddities from Northeast Wales by Gordon Emery).

These four pictures show the gradual decline of Dyserth Mill - already a ruin in the first picture from 1905. The mill building was finally demolished in 1952. The mill house, to the right of the mill, was demolished in 1981. For larger pictures see the Lower Dyserth Waterfall & Mills section of the Old Photo Gallery.

Marian Mills - Including Grove Mill

By the end of the 19th century there were apparently at least seven mills along the Afon Ffyddion within Dyserth parish, though not all were still in use. The majority of these were flour mills but two were fulling mills, where locally produced cloth was soaked in a mixture of water & fuller’s earth and pounded with wooden fulling hammers driven by a waterwheel. The cloth was then stretched out on tenter-frames (attached by tenter-hooks) and left to dry.
A full description of the process can be found at http://www.btinternet.com/~rob.martin1/full/full.htm

One fulling mill, called Pandy Mill, was situated behind what is now Grove Mill Cottage, near Marian Mills. This cottage once displayed the date of 1794, though it is no longer visible. I believe this mill closed between 1840 & 1850.
The cottage was apparently renamed Grove Mill Cottage when occupied by a later owner of Grove Mill - a newer mill (erected in 1815) further down the road towards Marian Mills. Grove Mill, for flour, closed in 1912, was re-opened in 1920 and finally closed five years later.

In the above picture - from a postcard posted in 1906 - the wheel of Felin Fach can just be seen on the left. It was demolished in 1947. The Marian Mills area became quite a tourist attraction in the early 20th century.

Llewerllyd Mill

According to Lucy Davies in her books on the village there is no early record of Llewerllyd Mill, but the building now converted to a private dwelling dates from 1785. It was the largest in the area and the longest-lasting in that it was working up until 1960, though latterly only for animal feed. It had a small, wide, undershot wheel which was fed from a pond filled from the Afon Ffyddion - the pond can be seen on the map at the top of this page, on the left.
