What is Juan Santamaría Day?

Costa Rica, lacking an army since 1948, doesn’t have many war heroes. The most notable exception is Juan Santamaría, a poor drummer boy from Alajuela. Santamaría helped thwart a notorious U.S. figure’s march through Central America during the mid-19th century.

Held every April, Juan Santamaría Day commemorates the Costa Rican victory in the Battle of Rivas in 1856 against the U.S. citizen William Walker and his mercenary army.

After overthrowing the government of Nicaragua, Walker set his sights on other Central American countries in hopes of developing a slave-trade empire. The Costa Rican government sent troops to Nicaragua to fight the growing threat.

It seemed unlikely that Costa Rica would win the battle until young Juan Santamaría set fire to a hostel where a number of Walker’s soldiers were staying. The fire led to a heavy loss in troops for Walker’s army, but also killed Santamaría. This act of heroism confirmed Costa Rica’s sovereignty and is celebrated every year with a parade and ceremony in Alajuela.
