Sacred Heart Catholic Church. Sacred Heart Church was established by the Oblates of Mary Immaculate for the English-speaking parishioners of Immaculate Conception Church. San Antonio architect Frederick B. Gaenslen designed this building for the new congregation in the Gothic Revival style. Dedicated in 1913, the structure served Sacred Heart until 1967, when parish boundaries were redrawn and it became a chapel of Immaculate Conception Cathedral. With its tall bell towers and pointed-arch stained glass windows, Sacred Heart is a noteworthy part of Brownsville's architectural history. Recorded Texas Historic Landmark - 2001 #12624
