A Night In Old San Antonio®” (NIOSA®) is a four-night festival in the heart of downtown San Antonio that celebrates the city’s diverse cultural legacy for more than 85,000 revelers annually. Sponsored by and benefiting the San Antonio Conservation Society, the 78th presentation of NIOSA will be held April 21-24, 2026, during the city’s Fiesta San Antonio® celebration.
NIOSA is the top fundraiser for historic preservation in the nation and truly lives up to its motto as a “Celebration for Preservation.” Funds raised enable the Conservation Society to continue its mission of preserving historic buildings, objects, places, and customs relating to the history of Texas and all that is admirably distinctive to the state. Out of the roughly $1.5 million netted at NIOSA, proceeds support restoration and preservation of historic properties and parks throughout the city, as well as education and advocacy programs and projects such as the Heritage Education tours, seminars, community tours, scholarships, the resource library, and the house museums. C-ROCK will be performing in the area called MainStreet USA
