The site, north of the Historic District, commemorates where America's first mass was celebrated. A 208-foot-tall stainless-steel cross (purportedly the world's tallest) allegedly marks the spot where the mission's first cross was planted in 1565. Also on the property is the Shrine of Our Lady of La Leche, the first shrine devoted to Mary in the United States. The landscape is exquisitely maintained, and the mission is crisscrossed with paths. A museum and gift shop are also on the property.
