Saint William Catholic Church

Saint William is at the heart of the city of Round Rock, TX, bringing God's Word and sacraments to His people. Growth, vibrancy, strength in the faith and in religious traditions -- these are but a few of the attributes of our parish.

A big family requires a big home, and Saint William is definitely a big family! With more than 25,000 parishioners, Saint William has been outgrowing its facilities throughout its storied history. The parish campus includes the Sacred Heart Chapel, where Perpetual Adoration is a cherished tradition, as well as an outdoor Stations of the Cross and Our Lady of Guadalupe Prayer Garden.
