Resumen: This chapter examines the international protection of places of worship. To this end, it begins by analysing how the establishment of such spaces is a manifestation of the fundamental right of freedom of religion. It also analyses the texts of the United Nations and European international bodies (the Council of Europe, the European Union and the OSCE) that call on States to defend the right of confessions to build their places of worship. The main difficulties that arise in the exercise of this right are identified. It also analyses the threats that these places suffer, which mainly come from religious radicalism, as well as from the respons - which is sometimes violent - to this radicalism.
