A brief history

Designed by architect O’Neil Ford, his plan featured a steel and concrete shaft with a multilevel "tophouse." Why was the tower built? In celebration of the Hemisfair World's Fair in 1968, this tower was erected to honor of San Antonio's 250th anniversary. The creation of the tower began in 1966 and was completed in 18 months. Check out the full construction timeline.

Fun fact: The HemisFair Executive Committee held a tower naming contest in 1966.
