Life in a Welsh Countryside
In 1950 Life in a Welsh Countryside, A Social Study of Llanfihangel-yng-Ngwynfa by was published. This was soon recognised as a classic study of the social structure and life in a predominantly Welsh speaking rural community in an upland area of Wales. This study describes the farms of the area, kindred relationships, customs and traditions, and the role of religion, particularly the chapels. In 2003 the Llanfihangel Social History Group published A Welsh Countryside Revisited: A new study of Llanfihangel-yng-Ngwynfa, which compares the changes that have taken place since the original publication, the decline in chapel attendance and the use of the Welsh language, which is now only spoken by slightly over half of the people in the village.
