Cultural property and places of worship are paradigmatic civilian objects and, as such, must not be the targets of attack in warfare. Article 52(3) of AP/I (quoted supra 365) expressly refers to places of worship and schools as the prototypes of civilian objects. The clause creates a presumption that these objects serve their normal civilian purposes, but it takes into account the possibility that they will be subjected to military use. Should the normal-civilian presumption be rebutted, even schools and places of worship may become military objectives.
