This book is based on original research and site visits extending from Cape Wrath (in Scotland) to the Transylvanian Alps. It is a cross-European study of the impact of religious belief on church architecture during the late sixteenth and seventeenth centuries. It is an interdisciplinary study, using religious architecture as means by which to examine the impact and influence of the Reformation and how it was tempered by vested interests and the nature of the religious settlement. It is the first attempt to examine the impact of a single religious confession on places of worship during the early modern period. It contains extensive illustrations.
