Signed into law in June 1992, Palo Alto Battlefield National Historic Site preserves the 3,400-acre scene of this clash between nations and informs visitors about its national and international importance. As the only unit of the National Park Service with a primary focus on the U.S.-Mexican War, Palo Alto Battlefield also interprets the entire conflict—including the details of its origins and the broad range of consequences. In an effort to turn a scene of conflict into a place of bi-national exchange and understanding, all research and interpretation conducted by the park reflects perspectives of both the United States and Mexico.
