A new church was designed by San Antonio architect Leo M.J. Dielmann and built by contractor Jacob Wagner in 1906. The current St. Mary's contains many Gothic features such as buttresses, trefoil motifs, and a corner tower rising high above the roofline. The interior contains extensive painting and murals, including on the organ pipes and ceiling vaults, leading to its inclusion in the National Register of Historic Places as a painted church. It is also part of the National Register's Fredericksburg Historic District, and a Recorded Texas Historic Landmark.The current campus also includes Our Lady of Guadalupe Catholic Church at 302 East College Street. Originally opened in 1919, it was closed in the 1940s, then reopened as a mission of St. Mary's for Spanish speakers in 1983.
