The St. Francis de Sales Oratory near downtown is an unquestionable jewel of the St. Louis landscape. It is a raiment of beauty, reflecting in a special way an ordering to the highest human activity, divine worship. This unites itself most intimately with the action of God, the ultimate exemplar of all beauty. In the dignity of the Neo-Gothic edifice and intricate decorations and in harmony with the sacred rites and music, the attributes of eternal Beauty are mirrored for all who visit. It comes as no surprise already many years ago the local chapter of the American Institute of Architects named the parish as one of the most significant historic buildings in Saint Louis.
St. Francis de Sales founded just after the end of the Civil War. The cornerstone of the original church was laid in 1867 by German immigrants who purchased a tract of land and made plans to build a resplendent church in the German Gothic style. The cost was $12,850, an enormous sum in those days. By the end of that year the first Mass was celebrated inside the imposing new church on Christmas Day while the building was still under construction.
