Heterotopia (space)
Heterotopia (from Greek ἕτερος, héteros 'different, other, distinct' and Greek τόπος, tópos 'place') is a concept elaborated by the 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": both similar to their surroundings, and contrasting with or upsetting them.
