Created by American Express and the National Trust for Historic Preservation, the Partners in Preservation program has provided $24 million in support of historic places across the U.S., helping historic places in eight cities to date, including San Francisco, Chicago, New Orleans, Boston, Seattle, Saint Paul/Minneapolis, New York, and Washington, D.C. region, and has engaged more than a million people.

Through this partnership, American Express and the National Trust for Historic Preservation seek to increase the public’s awareness of the importance of historic preservation in the United States and to preserve America’s historic and cultural places. The program also hopes to inspire long-term support from local citizens for the historic places at the heart of their communities.

In 2019, to mark the upcoming 100th anniversary of the passage of the 19th amendment, Partners in Preservation emphasized historic buildings and sites that celebrate the contributions of women in Main Street communities across America, both historic and modern day. Through this, Partners in Preservation uncovered and raised awareness of women's often unrecognized contributions to American history and society.
