On May 8, 1846, U.S. and Mexican troops clashed on the prairie of Palo Alto. The battle was the first in a two-year long war that changed the map of North America. Although the two countries have developed strong bonds and friendly ties since the war ended in 1848, these neighbors continue to contend with the legacy of the war.
No entrance fee.
