Amaz­ing flash­mob in front of my one of my favourite public buildings/squares: Peter Cels­ings Kul­turhuset in Stock­holm (1966-1971).

You could call Centre Pom­pi­dous (1972-1976) pro­gram­matic qual­i­ties a mere copy of it. In my opin­ion Kul­turhuset works even better, the low­ered square con­nects dif­fer­ent pedes­trian routes and tun­nels them under a major street.
The ini­tial design also marks all the func­tions by let­ter­ing them on the facade: OMA’s dia­grams of the 90′s.
