May 1 – 6, 2018 is designated as Commemorative Week, to celebrate key milestones exactly 300 years later: On May 1, 1718 the Mission San Antonio de Valero – later known as the Alamo – was established.

Four days later the Presidio San Antonio de Bejár was formed to protect the new mission. San Antonio’s five area missions are Texas’ only UNESCO World Heritage site and will be at the forefront of many activities during the Tricentennial year.

Before the missions were built, the area was inhabited by the Payaya people and known by them as Yanaguana. San Antonio’s multicultural history will be honored during the Commemorative Week. All year, there have been events around town celebrating the unique and diverse culture of San Antonio.

San Antonio and Bexar County will commemorate its 300th anniversary. History and education, arts and culture, and community service will be at the forefront of initiatives that will reflect on our storied past, celebrate our current achievements, and prepare the community for the next 300 years.


Key themes for each day during the commemorative week includes:

May 1: Day of Reflection

May 2: History & Education

May 3: Founders’ Day

May 4: Arts for All

May 5: Legacy Day

May 6: Military Appreciation & Commemorative Siclovia
