Approximately 35,000 visitors attend our fun-filled, family festival on the final Saturday of Fiesta® San Antonio each year. The King William Fair is the primary fundraising event for the King William Association, a non-profit organization which works to preserve and protect the oldest residential historic district in Texas and promote the unique cultural heritage of San Antonio. 

Beginning with a delightfully funky parade, the day-long event offers a variety of art and craft vendors, lively music, dance, Kids Kingdom play area, and delicious food and beverages. But what really sets this event apart is the sparkling beauty of its historic setting near the heart of downtown San Antonio, where the King William neighborhood entices Fairgoers to relax and unwind along shady, tree-lined streets adorned with stately Victorian homes, cozy cottages, and gracious gardens.
