The core interest of the Rhydymwyn Valley History Society is the operation of the former Valley Works at Rhydymwyn in Flintshire, Wales, and the involvement of Tube Alloys in the site.

The Rhydymwyn Valley History Society had its first informal meeting in May 2008, when about ten people attended. It currently has over 1100 members and new members are always welcome!

The many strands and consequences which have sprung from this period have led to a study of the relevant events from 1905 and the many diverse related topics, including the development of atomic power and bombs, chemical and biological weapons manufacturing, storage and disposal, the social history of our times and the fascinating plans considered and implemented during the Cold War.

It is a story of wartime directed labour and billeting, the enfranchisement of female labour, the involvement of common people in a worthy, but distasteful, duty and in many ways a wonderful story where life was consistently difficult until the Coronation Year, when we started to prosper as a united nation. It is not, in any way, an attempt to glorify war or to condone militarism.

This website is dedicated to telling a number of stories about the Valley Works at Rhydymwyn from various sources, including oral histories, government records, press reports, TV and radio sources and many other inputs.
