Archigram was an experimental architecture group formed in the 1960s in London. The group is known for producing conceptual designs for walking cities, instant cities, and plug-in cities that incorporated emerging technologies and drew inspiration from pop culture and science fiction. Their designs represented a rejection of the austerity and formality of postwar modernist architecture in favor of mobile, flexible cities that celebrated technology and consumerism. Their conceptual projects were published in Archigram, an avant-garde magazine they founded, helping them gain prominence and influence architectural thought in the 1960s and beyond.
