The Goldring/Woldenberg Institute of Southern Jewish Life (ISJL) has created an extensive entry on the history of Judaism and Jewish communities in San Antonio: "Encyclopedia of Southern Jewish Communities - San Antonio, Texas". For that reason, we won't include a history on this page. The above link is recommended instead!
There are several locations in San Antonio where Judaism is represented:
