Step inside the Cathedral Basilica of Saint Louis and the scale of what covers the walls, ceilings, and domes takes a moment to register. Mosaic. Everywhere. More than 41.5 million pieces of glass tesserae in over 7,000 colors cover 83,000 square feet of interior surface, making this one of the largest mosaic collections in the Western Hemisphere. The effect is overwhelming: biblical scenes, saints, and symbolic imagery rendered in shimmering glass that catches and scatters light from every angle. The building took seven years to construct, but the mosaics took 76 years to complete, a multi-generational artistic project that began when the cathedral opened in 1914 and continued until 1988.
