Many thanks for giving me the opportunity to zoom myself into FRIAS for an afternoon! My title is inspired by the letters of the Lüne nuns which I’m currently editing and where they eloquently speak in praise of their enclosure as the perfect rose-garden. When I saw the poster – thanks to Verena Spohn for choosing it! – it occurred to me that the religious enclosure is only one of the confined medieval spaces with positive connotations. So I will talk about three forms of enclosed space: starting with the castle, going on to the cell, ending with the study.
