led to demand for the mineral deposits in the Alyn valley and an increase in population of local villages, including Rhydymwyn. From the mid-18th century, Rhydymwyn was the site for a range of industries, which included foundries, waterwheels as well as mine workings. The new parish of Rhydymwyn was created on 31 March 1865, comprising: parts of the townships of Gwysaney and Gwernaffield, formerly in the parish of Mold; parts of the townships of Cefn and Glust (or Llysdianhunedd), and the whole of the township of Mechlas, formerly in the parish of Cilcain; and part of the township of Caerfallwch, formerly in the parish of Northop. The foundation stone of the new parish church, dedicated to St. John the Evangelist, was laid on 1 August 1861, and the church was consecrated on 17 September 1864. It has been designated a grade II* listed building. The Ministry of Supply (M.S.)

The Denbigh and Mold Junction Railway had a Rhydymwyn station on the south side of A541, which opened on 6 September 1869. The station closed to passengers on 30 April 1962 and completely from 4 May 1964. The former station building is now a private house.


Ffynnon leinw

Approximately from Rhydymwyn is the small hamlet of Hendre. Along the main road from the old Sardis Chapel, and only a few feet from the edge of the A541, there is an ancient well – Ffynnon leinw – (leinw comes from the Welsh word "llanw" meaning tide as it is reported that the water in the well rose and ebbed with the tides of the Dee Estuary). The well has been listed as one of the holy wells of Wales on a par with the more famous St Winefride's Well in Holywell. The well in Hendre is mentioned by

This work was inspired by the beauty of the countryside. During the same visit, Mendelssohn composed his operetta '' Son and Stranger''. Charles Kingsley, author of '' The Water-Babies, A Fairy Tale for a Land Baby'', also came and walked the Leete; both his and Mendelssohn's visits are commemorated by a plaque in Nant Alyn Road, Rhydymwyn.

In 2002 and 2003, DEFRA's internal team in two phases created a flood alarm and protection scheme to protect the whole village and Valley Works, with a level of protection in excess of a flood with a 1% chance of occurring in any one year. The total cost for the scheme was £88,000.
