The Rhydymwyn Valley History Society was founded in May 2008 and its core interest is the operation of the Valley Works at Rhydymwyn and the involvement of Tube Alloys in the site. It is a story of over 2,200 people in wartime directed labour, and billeting, the enfranchisement of female labour, the involvement of common people in a worthy, but distasteful, duty. It is not, in any way, an attempt to glorify war or to condone militarism.

The information on this site is contributed by members of the Rhydymwyn Valley History Society. We currently have over 1,200 members and new members are always welcome! We welcome everyone who wishes to become involved, irrespective of age, gender, sexual orientation, race, colour, ethnicity, political persuasion, religion or belief.

We have ambitious plans which need funding. Our sole income, except for occasional grants, depends on donations (most of which come from Open Days and Guided Tours). The residue comes from initial subscriptions and annual donations from our members. We ask that, if you think we provide value, you support us further by contributing?
