Archdiocese Moves Centennial Celebration to Greehey Arena
The Archdiocese of San Antonio will hold its 100th anniversary Mass indoors Saturday after weather forecasts prompted the move from Wolff Stadium.
Updated on Nov. 7, 2026 in Catholicism
The Archdiocese of San Antonio has moved its centennial celebration from Wolff Stadium to Greehey Arena on the St. Mary's University campus on Saturday afternoon. Archbishop Gustavo García-Siller made the decision due to consistent inclement weather forecasts.
Why it matters
The celebration marks 100 years since the archdiocese was established and will feature the announcement of a new archdiocesan pastoral vision. The change means attendees who registered for Wolff Stadium do not need to register again.
The archdiocese oversees 135 parishes across 19 counties and serves about 1.1 million Catholics, according to the archdiocese's own figures. Doors open at 3 p.m. Saturday, the procession begins at 3:30 p.m., and Mass starts at 4 p.m., with admission free.
