This chapter examines the transition of pagan architecture and religious practices in Late Antiquity, focusing on the treatment of Roman temples under Christian emperors. Drawing on legal texts, literature, inscriptions and archaeological findings, it evaluates whether temples were preserved, repurposed or destroyed. Challenging the common assumption of widespread temple destruction, it argues that such actions were neither systematic nor state-enforced. Instead, the chapter presents a nuanced perspective, demonstrating that many temples remained intact and were gradually adapted for secular or Christian purposes. Archaeological evidence suggests that abandonment and natural decay played a greater role in their decline than deliberate demolition. It also highlights how Christian emperors often sought to suppress pagan rituals while preserving architectural heritage, with legal measures typically prohibiting sacrifices rather than mandating temple destruction. By emphasising regional variations in temple transformations and critically assessing sources that exaggerate instances of destruction, the chapter challenges traditional narratives, offering a more complex understanding of religious and architectural change in Late Antiquity.
