Fiesta San Antonio started in 1891 as a one-parade event as a way to honor the memory of the heroes of the Alamo and the Battle of San Jacinto. It has evolved into one of this nation’s premier festivals with an economic impact of more than $284 million for the Alamo City. Fiesta is the Party With a Purpose. and the funds raised by official Fiesta events provide services to San Antonio citizens throughout the year. That commemoration still takes place, but for more than a century, Fiesta has grown into a celebration of San Antonio’s rich and diverse cultures. 2017 marks Fiesta's 126th anniversary!
