The south Wales landscape is marked by numerous chapels, places of worship (past and present) of the various Christian Nonconformist congregations. The Baptist congregation at Ilston, Gower, moved to Swansea, Massachusetts, but after the restoration of the Anglican worship with the issue of the Book of Common Prayer in 1662, several "gathered" churches survived belonging to the Baptist, Independent and Presbyterian denominations. In the 18th century members of some of these congregations became dissatisfied with the theological innovations of some trained ministers, and created new congregations such as that at Hengoed near Ystrad Mynach. In the same century, churches were sometimes involved in the Methodist movement, especially at Groeswen and Watford near Caerphilly, which both received frequent visits from John Wesley The largest denomination, however, became the Calvinist Methodists (later the Presbyterian Church of Wales), whose distinctive grey stone chapels can be seen in many parts.
