Cité de l'architecture et du patrimoine
Paris


A tribute to Paul Chemetov (1928-2024)
At a time when many modern buildings are threatened with disappearance or radical transformation, this study day explores the dilemmas between adaptation and preservation, memory and reinvention, through emblematic cases from the 1960s and 1970s.
Piacé le radieux will be taking part in a round-table discussion on modular architecture.
