Community Archives Wales
In 2007 the Troedyrhiw Environment Forum joined the Community Archives Wales programme. The Environment Forum is a part of the Troedyrhiw Community Partnership which has approximately 30 registered members who attend all kinds of different forums including a Residents Association, Scouts Group and Old Age Persons Group.
The Environment Forum is extremely active in engaging with all parts of the community and involving members in a range of community projects, such as the Trevithick Heritage Trail, completed recently with the assistance of Cyfarthfa Castle and Museum. The Community Archives Wales project will be an inter-generational one, as the older residents of the Environment Forum intend to work with the local Scouts Group to research the local history of Troedyrhiw, which will include the history of the Scouts, who, this year, are celebrating their centenary. The group has a keen interest in history and sharing their stories, and fully intend to involve all members of the community in the CAW project.
