This is an outline of philosopher Michel Foucault's concept of heterotopia or other spaces which he discussed in ‘Des Espaces Autres’ a radio broadcast in 1967. For Foucault heterotopia are real spaces that co-exist along side our everyday spaces but we consider them to be other in some way.

I am by no means an expert in Foucault, but this idea had resonance with my work. I presented a version of this talk at the Greenman Festival as part of the Einstein Talks in 2010. In that version, I applied Foucault's concept to the festival tent.
