On 5 April 1968, San Antonio opened the gates to Specialised Expo “Hemisfair ’68”, which marked the 250th anniversary of the city’s founding. The event, which gathered 6 million visitors under the theme “The Confluence of Civilizations in the Americas”, was a key moment for San Antonio, transforming the heart of the city.

This weekend, within the framework of its tricentennial celebrations, the Texan city commemorates 50 years of the Expo that celebrated cultural diversity across the western hemisphere. Demonstrating the Expo’s lasting impact, the anniversary is being marked by a range of activities within the former Expo site – HemisFair Park – and a number of buildings dating from the event, most notably the emblematic Tower of the Americas.
