I don't recall seeing mention of this site on the list before, and it may be
of interest to list members:
http://website.lineone.net/~dyfival1/histchapels.htm
Has a list of all the old chapels in the Dyfi Valley with comments about
their current uses
From a link to another URL on this site, I'm not sure if it is
part of the
same site or just by the same author, there are details of other
offerings of
genealogical interest such as old maps and tithe maps for the Dyfi valley area.

All the best
