Perth (Porth?) Primitive Methodist chapel

The 1878 Primitive Methodist magazine records  the laying of the memorial  stones for a new Primitive Methodist chapel at Perth in the Pontypridd station

When I wrote this page  I asked “Where was the chapel – in fact, where was Perth! What happened to the chapel?”. Thanks to Philip Thornborow (see comments) for a very plausible suggestion.
