The parish of Immaculate Conception, officially Ecclesia Immaculatae Conceptionis Beatae Mariae Virginis:  Immaculate Conception of the Blessed Virgin Mary, had its founding back in 1854.  Following, the independence of Texas in 1836 and its subsequent statehood in 1846, eight years later the faithful of this area dedicated their Church to the honor of the Blessed Virgin Mary.  It's history is intimately tied to the chapel of Nuestra Senora de Loreto, Our Lady of Loreto, at La Bahia, located at the Presidio La Bahia.  Established in 1749, The chapel predates the parish church, and is the oldest continuous use Catholic Chapel west of the Mississippi River.  Owned by the Roman Catholic Diocese of Victoria in Texas, it is the only diocese in possession of Spanish fort in the United States. 

The first church was built on land bought in 1892, directly across the street from the present Immaculate Conception Church building built in 1962.  The land on which the present church is located was bought in 1945 and had a two story house on it that served as a school.  The top floor being the convent, the lower being the school.  A new school was built in 1952, and now serves as the parish catechetical center.  

On December 6, 1899, the parish bought a plot of land to be used as a cemetery, now known as Holy Cross, which is across the street from the historical Oak Hill Cemetery.

The title of Immaculate Conception, refers to the teaching that Mary was conceived in the womb of her mother Anne, free from original sin by virtue of the merits of her son Jesus.  It was declared a dogma of the Church in 1854 by Pope Pius IX.  The feast is celebrated on December 8.  
 
The parish is celebrating her 165th year this year, 2019.  It continues the work of handing on the faith to the next generation, until our Lord Jesus Christ comes again in glory.
