The last decades have seen great scholarly interest in the fate of Roman temples and cult statues during the Christianisation of the Roman Empire. The surge of studies on spatiality and lived religion in Roman studies have demonstrated that ancient religious practice was not confined to sanctuaries but rather infused into all spheres of everyday life. Informed by these studies, I argue that the Christianisation effort was not confined to temples and cult statues in sanctuaries, despite the narrow focus on these monuments in legal and patristic sources. The spaces where people most frequently moved, lived, and practised religion in their everyday lives were equally important religious arenas. In this article I venture out of the temples and into the streets of late antique Ephesus to the Triodos intersection to highlight an array of subtle transformations that are unassuming in isolation, but together effectively Christianised the streetscape. I demonstrate that streetscapes were arenas of material Christianisation alongside monumental sanctuaries. The Triodos is used as a point of departure to show how the Roman streetscapes functioned as more-than-material religious assemblages. Human–material interaction in ritual and everyday movement and practices made the streetscapes active participants in the Christianisation process.
