Commemorating Tucson’s history and celebrating its bright future.
About Tucson 250+
Tucson 250+ is a year-long celebration honoring over 4,000 years of history, heritage, and culture in Tucson and Pima County. This milestone commemorates the 250th anniversary of Presidio San Agustín del Tucson in 1775 and recognizes how its foundation shaped Tucson’s trajectory and how that influence continues today. The plus (+) honors the Indigenous people and diverse communities that shaped the region long before and after its founding.
This anniversary is an opportunity to reflect on the intersection of hope, resilience, and human endeavor—both among those who sought to establish a new frontier and those whose lives were deeply tied to the land. Tucson 250+ includes events throughout 2025, leading up to a major celebration on August 23, 2025, at the Presidio Museum—the birthplace of modern Tucson. This website is a place to find event details.
The Tucson 250+ website is made possible through a collaboration between the City of Tucson, the Tucson-Pima County Historical Commission, the Arizona Historical Society, Los Descendientes de Tucson, the Presidio Museum, the Southern Arizona Transportation Museum, and the Vail Preservation Society.
Join us in celebrating the rich history and diverse culture of Tucson and the surrounding region!
