Historical Facts About San Diego

In 1542, A Portuguese Explorer Was The First European To Land On The West Coast 

The city’s beginnings trace back to when Portuguese explorer Juan Rodriguez Cabrillo claimed the area for Spain. It’s one of the important facts about San Diego and its origins.

Cabrillo’s exploration paved the way for future Spanish expeditions and laid the foundation for Spain’s eventual colonization of California, significantly influencing the area’s history and eventual incorporation into the United States nearly 200 years later. His journey remains a crucial moment in the early exploration and European presence on the West Coast.

In 1769, A Spanish Explorer Led An Expedition To Alta California 

A Spanish explorer named Gaspar de Portola led an expedition to Alta, California, which included San Diego, along with Franciscan friar Junípero Serra.

On July 16, 1769, they founded the first European settlement on the West Coast of the United States, Mission San Diego de Alcalá. 

This marked the beginning of Spanish colonization in California, almost 200 years after Juan Rodríguez Cabrillo’s claim.
