Heterotopia is a concept elaborated by philosopher Michel Foucault to describe certain cultural, institutional and discursive spaces that are somehow ‘other’: disturbing, intense, incompatible, contradictory or transforming. Heterotopias are worlds within worlds, mirroring and yet upsetting what is outside. Foucault provides examples: ships, cemeteries, bars, brothels, prisons, gardens of antiquity, fairs, Muslim baths and many more. Foucault outlines the notion of heterotopia on three occasions between 1966-67. A talk given to a group of architects is the most well-known explanation of the term. His first mention of the concept is in his preface to 'The Order of Things' and refers to texts rather than socio-cultural spaces.
