Chapels of Onllwyn
Onllwyn is situated in the Dulais Valley between Dyffryn Cellwen and Seven Sisters. Today, there are no places of worship located within Onllwyn.
In the past, Onllwyn Chapel was located in the village. The West Glamorgan Archive includes records both for an "Onllwyn Chapel" and for an "Onllwyn Congregational Church". Whether these are separate establishments is not at the moment clear.
A couple of pictures from external websites can be viewed at:-

www.oldneath.co.uk which shows Onllwyn Chapel, c1960, though you need to join the site in order to see the full-sized version.
