This book explores a resource for audiences and performers possibly unique in the United Kingdom and largely unheard of even within the Performing Arts fraternity. For the first time, the entire estate of theatre and performance buildings in Wales has been identified and brought together revealing itself as a single incredible cultural heritage asset. The histories of each building have been researched and the author has described from a Theatre Architect's perspective and recorded with extensive photography 111 buildings in South Wales that are being, or were, used for theatre and other forms of public live entertainment over the last 150 years. Details of a further 47 theatre buildings that have already been demolished and lost forever are also included. This is an essential reference book for anyone interested in the buildings within which performing arts are presented in the region, whether as building owner or operator, performer, audience member, local or National Politician or policy maker, Architect or Theatre Consultant.
