The Cwm Dulais Historical Society, established in 1964, is dedicated to exploring history, with a special focus on sparking interest in the rich local history of the Dulais Valley in South Wales. This society primarily serves the villages of Coelbren, Banwen, Dyffryn Cellwen, Pantyffordd, Seven Sisters, and Crynant, and it also reaches out to Cilfrew and Aberdulais. Sadly, the society is currently operating on a limited basis due to a shortage of active members.
