Sanctuary cities have experienced a strong political and theoretical revival in the last decade. However, the focus on cities and their policies restricts the idea of sanctuary to its urban, legal andto a certain extent -North American enactments, leaving dispersed and rural forms of sanctuary understudied. In this paper, I examine the sanctuary spaces and practices in the Roya Valley, at the border between Italy and France, and more particularly the journey of its most well-known activist, the farmer Cédric Herrou. Although Herrou's first actions could be best described as humanitarian and hospitable help towards migrants, they gradually evolved into more structured solidarity actions. These led to a decision by the Constitutional Council that strengthened the French constitutional value of fraternity to better distinguish disinterested support from human smuggling motivated by profit. I argue that these three concepts of fraternity, hospitality and solidarity identify different repertoires of sanctuary that respectively fulfil functions of signalling, protecting and community-building. These different functions, when articulated together, constitute a sanctuary or network of safety. By reconstructing this series of practices and justifications, I aim to clarify the conceptual vocabulary and normative appeal of sanctuary.
