Outside Sweden, Jan Gezelius is perhaps best known for three museums: the little migratory birds museum at Öland, 1961; the ethnographic museum at Stockholm, 1972–78; and the archaeological museum at Eketorp, 1977–82. Here he talks about his houses and his architectural ideals. This paper is a translated and edited version of part of an interview in Jan Gezelius edited by Claes Caldenby and Åsa Walldén and published by Arkitektur Förlag/Arkus in 1989.
