Rather than speak of the identity of European architecture, an unworkable and perhaps incorrect notion for a continent that speaks at least twenty languages, Lotus has embarked on a very special venture by drawing up a list of decisive works of what we can justifiably call modern European architecture. This undertaking, essentially the draft of a corpus, has revealed some features of an experience that make it unique in the international panorama. The ten cases chosen are in fact all distinguished by a marked intellectual and ideal character aimed at reinventing the connection between architecture and society, architecture and city, architecture and environment: this for us is the heritage of Europe. The corpus of works is being presented for discussion and its “openness” does not prevent us from tracing lines for the future development of contemporary architecture. In fact the diaspora of this European experience may be destined to enrich the architecture of many of the world’s nations.
