20th centuries, there was a vigorous literary and musical culture centred round eisteddfodau. Despite a few timid attempts to emulate this literature in English, it can be argued that few writers seem to connect with either the landscape or the literary tradition. The one exception, to some extent, can be considered to be Dylan Thomas. Religion 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. These were mainly Welsh-language congregations. Anglicanism in South Wales became autonomous from the Church of England with the Welsh Church Act 1914, but the immediate demise of the denomination feared at that time has not taken place in the Church in Wales. There are a number of Brethren Assemblies in Cardiff and in the Swansea area and Free Presbyterian Churches in Rhiwderin, near Newport and at Merthyr Tydfil. The Roman Catholic community, despite systematic persecution, survived in the 17th to 19th centuries, especially in Brecon and among minor gentry such as the Vaughans of Welsh Bicknor, on the Monmouthshire–Herefordshire border. Among members of foreign origin of later urban Catholic congregations were the Bracchi, Italians in the café and catering trades often from Bardi in the Apennines. Post-war diversity has brought mosques, especially in Cardiff and Newport, Sikh gurdwaras, including one on the mountain near Abercynon and a growing number of Evangelical and Pentecostal congregations. These often add a strongly international element into local life, such as the "Pont" twinning project between Pontypridd and Mbale, Uganda, and the creation of "Fairtrade" relationships with primary producers worldwide.
