Preserving the Recent Past 4 

March 19-22, 2025
Boston, Massachusetts

In 1995, Preserving the Recent Past–the first national conference to examine the evaluation and preservation of twentieth-century resources–was held in Chicago, Illinois. It was during this event that a US chapter of Docomomo International held its charter meeting. In honor of our 30th anniversary, Docomomo US is partnering with the Historic Preservation Education Foundation (HPEF) to host Preserving the Recent Past 4 (PRP4) in 2025. This event will be in lieu of the National Symposium. 

PRP4 offers a national forum to share the latest strategies for identifying, protecting, and conserving significant structures and sites from the recent past.

Docomomo US and its local New England chapter will take part in the paper selection process and will take the lead in organizing the unique tours we are known for. And we wouldn't miss a chance to throw a party!

All conference information and registration will be available through PRP4 website. 

The Call for Proposals is now open. Deadline is September 15, 2024.

Sponsorship opportunities are now available.

2026 Docomomo International Conference

Los Angeles, California

The biennial Docomomo International Conference is headed stateside! For only the second time ever, the conference will be hosted by Docomomo US. We expect this event will be larger than our typical National Symposium audience. Attendees can look forward to exciting venues, rigorous academic sessions, networking opportunities, social events, and the Docomomo tours you know and love. Conference proceedings will be produced.

Start planning now to join your international colleagues in LA in 2026 and stay tuned for more details coming soon.

Thank you to everyone who joined us in Miami for the 2024 National Symposium, and especially to the sponsors and partners listed below who helped to make the event such a success.

The Docomomo US National Symposium is the primary event in the United States for professionals to discuss and share efforts to preserve modern architecture and meet leading practitioners and industry professionals.

The Symposium developed as a result of the Docomomo US Board of Directors’ annual “Face to Face” meeting. The first expanded event took place in Los Angeles in 2010 with an open forum for local individuals actively engaged in the discussion of modern architecture. Docomomo US hosted its first National Symposium in Sarasota, Florida in April 2013. Held annually, this multi-day conference seeks to engage local participants in cities across the United States, offering participants the ability to interact with and explore a wide variety of significant modern architecture and sites.
