Spaces of Peace. Castles, Churches, Courts, Markets Certain spaces and persons need a higher protection if they play an important role in society or are particularly exposed to danger. In the Middle Ages special peace regulations applied to castles, law courts, churches, markets, women, and so on. A ‘castle peace’ was sworn by thosewhoowned a castle incommonin order to keep the castle safe. From the thirteenth century, castle pacts were found in the west and southwest of the Holy RomanEmpire andsome of them developed into extensive associations of lesser nobles. In the early modern period, with the general pacification of the empire, the significance of such special agreements diminished. In some noble families a ‘castle peace’ sometimes became a set of inheritance rules; some such agreements also endured as basic sets of rules governing the nobles of a principality or a territorial condominium.
