Mexican Fiesta has called Henry Maier Festival Park home almost as long as Summerfest has. Starting on the south side in 1973, the fiesta moved to the lakefront grounds in 1977. The longstanding event is rooted in pillars of community, education, Mexican heritage, and cultural advancement. Unlike Summerfest, which begins next week, Mexican Fiesta will not require proof of vaccination or a negative COVID-19 test for entry.
