Alto Battlefield National Historic Site
May 8, 1846 troops of the United States and Mexico clashed on the
prairie of Palo Alto in the first battle of a two-year war.
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.
