For four days in July of 1911, San Diego held a series of events to celebrate the Exposition’s groundbreaking along with the history of California and San Diego.
View the program for the four-day Groundbreaking Ceremony.
The Groundbreaking Ceremonies were described by John McGroarty in great detail in the book San Diego and Imperial Counties, California by Samuel F. Black.
Another excellent description of the Groundbreaking Ceremonies was printed in the Bulletin of the Pan-American Union.
