As well as the prolific growth of pits and mines throughout the Rhondda Valleys from 1850 onwards, the other type of explosive growth which occurred was in the field of religion. The churches and chapels were the few places outside the billiard halls and pubs were people could readily meet Also it was a means whereby immigrants from the same part of the world could easily congregate.

These are but a few of the many churches and chapels that are and have been in the Rhondda Valleys. If you have any others to add to the list me let me know.
