The first Saint Mary's Church, Warwick is a substantial sandstone building, constructed 1863–1865 to designs of prominent
Brisbane architect, Benjamin Backhouse. Various people, including Michael Knole, William Cowper and Sarah Ransley acquired the various future church lots (Allotments 7–12 of Section 49) by Deed of Grant on 16 August 1860. By September 1863, John Cani and
James Quinn, the parish priest and
Bishop of Brisbane respectively, became the registered owners of these allotments. The plan for the church was duly prepared by prominent Brisbane architect, Benjamin Backhouse, to the specifications that it was to be simple but tasteful, in the
Gothic style and in stone or brick. Benjamin Joseph Backhouse arrived in Brisbane in May 1861, and designed many buildings of architectural pretension in Queensland over the next six years, before he departed for
New South Wales by 1868. He was responsible for the design of many churches including the second
St Stephen's Roman Catholic Cathedral in Brisbane, additions to St John's Pro-Cathedral in Brisbane, as well as many other smaller regional churches. Despite the setback of severe damage during a thunder storm the church the building was officially opened on 23 August 1865 by Bishop Quinn, the first
Roman Catholic Bishop of Brisbane. At this time the church was named the
St Mary of the Assumption, now popularly shortened to St Mary's. This original building consisted of only the
nave of the present church, with side entrances, not through
porches, but simply accessing the body of the church directly. The roof of the building was slated or shingled. The contractor was CA Doran and the structure cost about . The stone for the construction of the church was obtained from the Sidling Quarries, which were a small group of quarries in Warwick. In 1865 Dr Cani was succeeded by Father Scortechini, who was soon after replaced by Father Hogan. By 1867 a Catholic school, run by the Misses O'Mara until the arrival of the
Sisters of Mercy in 1874, was established in the church by the next parish priest, Father O'Reilly. The church was partitioned with calico screens, firstly to separate the
sanctuary from the teaching area and, later to divide the teaching area into smaller rooms in the body of the church. O'Reilly was replaced by Father McDonagh, who was the first resident priest, and after him in 1876 came Father
James Horan who was to remain in Warwick until 1905. Horan was responsible for the completion of the church by 1894, when the
transepts and
chancel were added. By this time porches over the side entrances were also completed. Monsignor Michael Potter was posted as a curate to Warwick in 1891, and continued there as the parish priest after Horan's death in 1905. It was Potter who decided that the original St Mary's Church was no longer adequate for the needs of his community. Thus he sought plans for the construction of a second larger church, further north on the same block in Palmerin Street. Local architects, Dornbusch & Connolly drew plans for the
second St Mary's church which, like the original church, was to conform to a
cruciform plan, but only the body has thus far been completed. The new church was constructed between 1920 and 1926, when it was officially opened. After the opening of the new church, the original St Mary's was partitioned, lined and used as school rooms, for the Catholic primary school which began in the building in its earliest days. It has remained as a community meeting hall and store to this day. == Description ==
