Salem Welsh Baptist Chapel, Senghennydd - Evan Roberts

Meanwhile, Mr. Evan Roberts, accompanied by Miss Mary Davies (Gorseinon), Miss Annie Davies (Maesteg), and Mr. M’Taggart, had gone to the Welsh Baptist Chapel, where there was a somewhat smaller congregation, and where the meeting was, for a time, decidedly colder— so cold, indeed, as to affect the young revivalist with deep emotion. He prayed and asked others to pray for a downpour of the Spirit, and presently there was a warmer feeling, the responses to the invitations to “confess” being numerous. From, 'The Western Mail', 7th December 1904.

The chapel has been demolished. I think this is the place - it is very close to the Grid reference I have found and it is a big building to fill what would have been a big space.
