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.

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

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.
