Adaptive Reuse of Roman Catholic Churches: Good Practice and Viable Solutions for Converting Sacred Spaces

This book examines the adaptive reuse of Roman Catholic churches through twenty-five case studies from Poland, Germany, the Netherlands, and Belgium. It addresses the complex intersection of theology, heritage conservation, and contemporary social needs and explores how sacred spaces can serve new secular purposes while preserving their spiritual, historical, and cultural significance. Integrating historical, theological, architectural, and policy perspectives, the book traces the historical evolution of church reuse, the impact of secularization, and the ethical responsibilities of architects, alongside the conservation principles that shape sacred heritage management. Theological reflections address ecclesiastical spatial symbolism, canon law, profanation, and episcopal guidelines in the selected countries. Comparative national profiles analyze religious demographics, church infrastructure, and property stewardship. Case studies illustrate diverse reuse models – from liturgical continuity to radical transformation – across cultural, social, commercial, residential, and interfaith contexts. The conclusions synthesize the findings, offering strategies that balance heritage preservation with contemporary functional needs. This publication is aimed at architects, historians, art theorists, architecture researchers, conservators, priests, and the managers of these buildings, as well as enthusiasts of sacred architecture who care deeply about its future, as the book is intentionally multi-layered and multi-dimensional.
