It commemorates the landing of Juan Rodríguez Cabrillo at San Diego Bay on September 28, 1542. This event marked the first time a European expedition had set foot on what later became the West Coast of the United States. The site was designated as California Historical Landmark #56 in 1932. As with all historical units of the National Park Service, Cabrillo was listed on the National Register of Historic Places on October 15, 1966.
