Mission Dolores Park
Until after World War II, the Mission District was largely inhabited by European Americans, which from the 1950s to the 1970s were replaced by an influx of Latino immigrants.

The "Mexican Liberty Bell" (today located in the National Palace in Mexico City) is a church bell that Hidalgo rang in 1810 in the Mexican city of Dolores Hidalgo, in what became known as the "Cry of Dolores" (El Grito de Dolores) that launched the Mexican War of Independence. In 2014, the replica was relocated by around 25 feet during the renovations of Mission Dolores Park.
