The 19th International Docomomo Conference in Los Angeles explored how modernism is anything but a placeless “white box,” foregrounding climate-responsive design, regional identity, and the conservation of experimental modern architecture. Through panels on “Modernism in the Sun,” case studies like Marcel Breuer’s precast facades and Sim Van der Ryn’s Gregory Bateson Building, and tours of works by Paul R. Williams, Charles Moore, and other California innovators, the conference highlighted “Multiple Moderns” shaped by local histories, materials, and communities—and the complex challenges of preserving them for the future.

Discover how Docomomo US/NOCA made 2025 a landmark year for modern architecture advocacy in Northern California, from defending Vaillancourt Fountain and shaping preservation policy to hosting tours, talks, and grants that engaged new audiences in the legacy of modernism.

Tour Day is the only national program of its kind, devoted to the appreciation of modern architecture in the United States. Tours and events focused on Modern Movement buildings and landscapes are hosted throughout October by Docomomo US chapters, partners, and local preservation advocates across the country.
