In the tradition of the European Gothic churches, St. Francis de Sales is adorned with a magnificent array of stained glass windows.
The church 130-foot long aisle, one of the longest of the churches in St. Louis, and its beautiful interior and solemn liturgy has made it a popular place for weddings. The church has four bells including one from the original church.
Gothic or pointed arches used inside the building create tall, open spaces and directs the eye skyward and giving the interior a grand appearance.
The interior features multiple apses, and richly carved wood, statues and details.
The church interior was designed as a German hall church with ceilings over the side aisles almost as high as those over the main aisle increasing the open feeling and spaciousness.
The High Altar and the reredos, the ornate screen behind the altar, are in a large apse. Smaller apses on the sides of the main apse feature altars to the Blessed Mother and to St. Joseph.
The transept projects from the side of the nave, feature altars to Our Mother of Perpetual Help to the North, and the Infant of Prague to the South.
The Baptistery features Byzantine-style glittering mosaics. It is the same artists who worked on the mosaics in the (new) Cathedral Basilica. Lapis Lazuli stone from Persia was used for the blue sky mosaic in the vaulted ceiling.
